Wild Flowers Poisonous Plants

"The Symbol P denotes a plant poisonous in greater or less degree to man in one or more of its parts at one or more seasons" from The Pocket Guide to Wild Flowers by David McClintock and R.S.R Fitter assisted by Francis Rose. Eleventh Impression 1978. (ISBN 0 00 219363 9). The plants with the Symbol P at the end of the line with their name on it in that book are shown in the following list.

Flora of the British Isles by A.R. Clapham, T.G. Tutin and E.F. Warburg. Cambridge at the University Press 1952. This book details the poisonous parts and toxicity of those poisonous plants native to the UK.

The Poison Garden website originated from John Robertson's role as the first Poison Garden Warden at the Alnwick Garden.

All the plants in this linked list are poisonous to animals.

Buttercup

Baneberry (Actaea spicata)

View photos in Wikimedia Commons

The berries contain cardiogenic toxins which can have an immediate sedative effect on human cardiac muscle tissue, and are the most poisonous part of the plant. Ingestion of the berries can lead to cardiac arrest and death. The berries are harmless to birds, the plants' primary seed dispersers.

Very poisonous

Nightshade

Bittersweet (Solanum dulcamara)

View photos in Wikimedia Commons

The poisons are the alkaloid solanine and the amorphous glucoside Dulcamarine. Solanine acts narcotically; in large doses it paralyses the central nervous system, without affecting the peripheral nerves or voluntary muscles. It slows the heart and respiration, lessens sensibility, lowers the temperature and causes vertigo and delirium, terminating in death with convulsions.
The berries have proved poisonous to a certain degree to children.

Very Poisonous

Yam

Black Bryony (Dioscorea communis, Tamus communis)

View photos in Wikimedia Commons

The large, fleshy root high in starch is black on the outside, very acrid, and extremely poisonous. Literature usually states that 15 red berries could be fatal to a child.

Very Poisonous

Nightshade

Black Nightshade (Solanum nigrum)

View photos in Wikimedia Commons

Like Bittersweet above, this plant contains the alkaloid solanine, which is very poisonous even in small amounts. It also contains atropine. These poisons produce the following symptoms:-

• Eyes, ears, nose, mouth, and throat
◦ Dry mouth
◦ Enlarged (dilated) pupils

• Gastrointestinal
◦ Diarrhea
◦ Stomach pain
◦ Vomiting

• Heart and blood
◦ Pulse - slow or rapid
◦ Shock

• Lungs
◦ Slowed breathing

• Nervous system
◦ Delirium
◦ Fever
◦ Hallucinations
◦ Headache
◦ Loss of sensation
◦ Paralysis

• Whole body
◦ Sweating

Very poisonous

Buttercup

Buttercup Family (Ranunculus species):-

Adderstongue Spearwort (Ranunculus ophioglossifolius)
Bulbous Buttercup (Ranunculus bulbosus)
Celery-leaved Buttercup (Ranunculus sceleratus)
Corn Buttercup (Ranunculus arvensis)
Creeping Buttercup (Ranunculus repens)
Creeping Spearwort (Ranunculus reptans)
Greater Spearwort (Ranunculus lingua)
Hairy Buttercup (Ranunculus sardous)
Ivy-leaved Crowfoot (Ranunculus hederceus)
Jersey Buttercup (Ranunculus flabellatus)
Lesser Celandine (Ranunculus ficaria)
Lesser Spearwort (Ranunculus flammula)
Meadow Buttercup (Ranunculus acris)
Scilly Buttercup (Ranunculus muricatus)
Small-flowered Buttercup (Ranunculus parviflorus)
Thread-leaved Crowfoot (Ranunculus trichophyllus)
Various-leaved Crowfoot (Ranunculus heterophyllus)
Water Crowfoot (Ranunculus aquatilis)
Wood Goldilocks (Ranunculus auricomus)

View photos in Wikimedia Commons

All Ranunculus species are acrid, poisonous and are dangerous to cattle, but are ordinarily avoided by all grazing animals. The poisonous constituent is probably anemonin.

Whole plant of Ranunculus arvensis (Corn Crowfoot) is poisonous, particularly the seeds. The seeds are mainly dangerous when ground among the wheat. Millers look out for it.

Buttercup

Columbine (Aquilegia vulgaris)

View photos in Wikimedia Commons

Its seeds and roots contain cardiogenic toxins, which cause both severe gastroenteritis and heart palpitations if consumed as food. Columbine poisonings may be fatal. Member of the poisonous Ranunculus family and Buttercup Wildflower family.

Highly Poisonous

Buckthorn

Common Buckthorn (Rhamnus cathartica)

View photos in Wikimedia Commons

The seeds and leaves are mildly poisonous for people and animals. The toxins cause stomach cramps and laxative effects that may function in seed dispersal. The chemical compounds responsible for this laxative effect are anthraquinone and emodin.

Poisonous

Umbellifer

Cowbane (Cicuta virosa)

View photos in Wikimedia Commons

The plant contains cicutoxin, which causes death by disruption of the central nervous system. In humans, cicutoxin rapidly produces symptoms of nausea, emesis and abdominal pain, typically within 60 minutes of ingestion. Poisoning can lead to tremors and seizures. A single bite of the root (which has the highest concentration of cicutoxin) can be sufficient to cause death. One gram of water hemlock per kilogram of weight will kill a sheep and 230 grams is sufficient to kill a horse. Due to the rapid onset of symptoms, treatment is usually unsuccessful.

Highly Poisonous

 

D

 

 

Nightshade

Deadly Nightshade (Atropa bella-donna)

View photos in Wikimedia Commons

 

The plant is harmless to rabbits, but people eating the rabbits die; hence rabbits are unsafe from May to September, when the plant is growing and fruiting.

Belladonna is one of the most toxic plants found in the Western hemisphere. All parts of the plant contain tropane alkaloids. The berries pose the greatest danger to children because they look attractive and have a somewhat sweet taste. The consumption of two to five berries by children and ten to twenty berries by adults can be lethal. The root of the plant is generally the most toxic part, though this can vary from one specimen to another. Ingestion of a single leaf of the plant can be fatal to an adult.

The active agents in Belladonna, atropine, hyoscine (scopolamine), and hyoscyamine, have anticholinergic properties. The symptoms of belladonna poisoning include:-
dilated pupils, sensitivity to light, blurred vision, tachycardia, loss of balance, staggering, headache, rash, flushing, dry mouth and throat, slurred speech, urinary retention, constipation, confusion, hallucinations, delirium, and convulsions.
In 2009, atropa belladonna that was mistaken for blueberries with six berries ingested by an adult woman was documented to result in severe anticholinergic syndrome. The plant's deadly symptoms are caused by atropine's disruption of the parasympathetic nervous system's ability to regulate non-volitional/subconscious activities such as sweating, breathing, and heart rate. The antidote for belladonna poisoning is physostigmine or pilocarpine, the same as for atropine.

Lethal

Spurge

Dog's Mercury (Mercurialis perennis)
Annual Mercury (Mercurialis annua)

View photos in Wikimedia Commons

Dog's mercury is highly poisonous. Methylamine (mercurialine) and trimethylamine are thought to be present, together with a volatile oil and saponins. Symptoms of poisoning appear within a few hours; they can include vomiting, pain, gastric and kidney inflammation, and sometimes inflammation of the cheeks and jaw, and drowsiness. Apart from Chenopodium bonus-henricus and some other edible members of the Chenopodiaceae (also known as mercuries), the most similar-looking species is probably Mercurialis annua (annual mercury), which is also thought to be poisonous.

Highly Poisonous

Spurge

Euphorbia Family:-

Broad Spurge (Euphorbia platyphyllos)
Caper Spurge (Euphorbia lathyrus)
Cypress Spurge (Euphorbia cyparissias)
Dwarf Spurge (Euphorbia exigua)
Hungarian Spurge (Euphorbia esula)
Irish Spurge (Euphorbia hyberna)
Petty Spurge (Euphorbia peplus)
Portland Spurge (Euphorbia portlandica)
Purple Spurge (Euphorbia peplis)
Sea Spurge (Euphorbia paralias)
Sun Spurge (Euphorbia heliocopia)
Tiatern Spurge (Euphorbia stricta)
Wood Spurge (Euphorbia amygdaloides)
Pencil Cactus or Milkbush (Euphorbia tirucalli)

The latex (milky sap) of spurges acts as a deterrent for herbivores as well as a wound healer. As it is under pressure, it runs out from the slightest wound and congeals within a few minutes of contact with the air. Among the component parts are many di- or tri-terpen esters, which can vary in composition according to species, and in some cases the variant may be typical of that species. The terpene ester composition determines how caustic and irritating to the skin it is. In contact with mucous membranes (eyes, nose, mouth) the latex can produce extremely painful inflammation. In experiments with animals it was found that the terpen ester resiniferatoxin had an irritating effect 10,000 to 100,000 times stronger than capsaicin, the "hot" substance found in chili peppers. Several terpen esters are also known to be carcinogenic.

Therefore spurges should be handled with caution. Latex coming in contact with the skin should be washed off immediately and thoroughly. Partially or completely congealed latex is often no longer soluble in water, but can be removed with an emulsion (milk, hand-cream). A physician should be consulted regarding any inflammation of a mucous membrane, especially the eyes, as severe eye damage including possible permanent blindness may result from acute exposure to the sap. It has been noticed, when cutting large succulent spurges in a greenhouse, that vapours from the latex spread and can cause severe irritation to the eyes and air passages several metres away. Precautions, including sufficient ventilation, are required. Small children and domestic pets should be kept from contact with spurges.

Poisonous

Umbellifer

Fool's Parsley (Aethusa cynapium)

View photos in Wikimedia Commons
 

Usually contains coniine and death is caused by respiratory paralysis. It is related to Hemlock and Water-dropwort, and like them, is poisonous, though less so than Hemlock. Poisoning from Fool's Parsley showed symptoms of heat in the mouth and throat and a post-mortem examination showed redness of the lining membrane of the gullet and windpipe and slight congestion of the duodenum and stomach. Since some toxins are destroyed by drying, hay containing the plant is not poisonous.

Poisonous

Figwort - mulleins

Foxglove (Digitalis purpurea)

View photos in Wikimedia Commons

Due to the presence of the cardiac glycoside digitoxin, the leaves, flowers and seeds of this plant are all poisonous to humans and some animals, and can be fatal if eaten.
The main toxins in Digitalis are the two chemically similar cardiac glycosides: digitoxin and digoxin. Like other cardiac glycosides, the Digitalis toxins exert their effects by inhibiting the ATPase activity of a complex of transmembrane proteins that form the sodium potassium ATPase pump, (Na+/K+-ATPase). Inhibition of the Na+/K+-ATPase in turn causes a rise not only in intracellular Na+, but also in calcium, which in turn results in increased force of myocardial muscle contractions. In other words, at precisely the right dosage, Digitalis toxin can cause the heart to beat more strongly. However, digitoxin, digoxin and several other cardiac glycosides, such as ouabain, are known to have steep dose-response curves, i.e. minute increases in the dosage of these drugs can make the difference between an ineffective dose and a fatal one.

Symptoms of Digitalis poisoning include a low pulse rate, nausea, vomiting, and uncoordinated contractions of different parts of the heart leading to cardiac arrest and finally death.

Hemlock (Conium maculatum)

View photos in Wikimedia Commons

All plant parts are poisonous. Conium contains the piperidine alkaloids coniine, N-methylconiine, conhydrine, pseudoconhydrine and γ-coniceine (or g-coniceïne), which is the precursor of the other hemlock alkaloids. The most important and toxic of these is coniine, which has a chemical structure similar to nicotine. Coniine is a neurotoxin, which disrupts the workings of the central nervous system and is toxic to humans and all classes of livestock. Ingestion in any quantity can result in respiratory collapse and death. Coniine causes death by blocking the neuromuscular junction in a manner similar to curare; this results in an ascending muscular paralysis with eventual paralysis of the respiratory muscles which results in death due to lack of oxygen to the heart and brain. Death can easily be prevented by artificial ventilation until the effects have worn off 48–72 hours later. For an adult the ingestion of more than 100 mg of coniine (approximately 6 to 8 fresh leaves, or a smaller dose of the seeds or root) may result in fatality.

Very poisonous

Nightshade

Henbane (Hyoscyamus niger)

View photos in Wikimedia Commons

0.03-0.15% tropane alkaloids (hyoscyamine, hyoscine = scopolamine), flavonol glycosides (quercitin, rutin, kaempferol), small amounts of volatile amines (choline, methylpyrroline, pyridine). have been found in the foliage and seeds of the plant. Common effects of henbane ingestion in humans include hallucinations, dilated pupils, restlessness, and flushed skin. Less common symptoms such as tachycardia, convulsions, vomiting, hypertension, hyperpyrexia and ataxia have all been noted.
Henbane can be toxic, even fatal, to animals in low doses.
Children have been poisoned by eating the seeds.

All parts, including the berries, are highly poisonous. Roughly 38 different cardiac glycosides (cardenolides) have been found in the plant, some among others:

  • convallarin
  • convallamarin
  • convallatoxin
  • convallotoxoloside
  • convallosid
  • neoconvalloside
  • glucoconvalloside
  • majaloside

  • 19-hydroxy-sarmentogenin
  • arabinosido-6-deoxyallose
  • lokundjoside

The plant also contains saponins.

If the plant is touched or handled, hands should be washed before doing anything else.

Highly poisonous

Arum

Lords and Ladies (Arum maculatum)

View photos in Wikimedia Commons

It contains the same oxalates as found in Arum italicum. These needle-shaped crystals can irritate the skin, mouth, tongue, and throat, resulting in throat swelling, breathing difficulties, burning pain, and stomach upset.

Though the orange berries are quite attractive, their acrid taste and the tingling in the mouth which begins quite quickly, mean that large amounts are rarely ingested and serious harm is unusual.

The plant is said to be one of the most common causes of accidental plant poisoning based on attendance at hospital A & E departments though this may be because the irritation of the tongue and mouth is more likely to result in hospital attendance than a simple stomach upset from, say, eating a daffodil bulb thinking it to be an onion.

Poisonous

Lily: Garlic

Meadow Saffron (Colchicum autumnale)

View photos in Wikimedia Commons

It is poisonous in all its parts which is due to the presence of the alkaloid colchicine - This can cause hypovolemic shock due to extreme vascular damage and fluid loss through the gastrointestinal tract, which can be fatal. This molecule, the structure of which has been determined has the IUPAC name: N-((7S)-5,6,7,9-tetrahydro-1,2,3,10-tetramethoxy-9-oxobenzo(a)heptalen-7-yl)- acetamide

Poisonous

Daphne

Mezereon (Daphne mezereum)

View photos in Wikimedia Commons

The fruit is a bright red berry. Daphnetoxin present in the berries and twigs is very poisonous for people, though fruit-eating birds like thrushes are immune and eat the berries, dispersing the seeds in their droppings. Handling the fresh twigs can cause rashes and eczema in sensitive individuals.

Very poisonous

Buttercup

Monkshood (Aconitum anglicum. Syn. Aconitum napellus)

View photos in Wikimedia Commons

All species are highly poisonous and have often proved fatal owing to the presense of the powerful and deadly alkaloid aconitine and of other associated alkaloids. Aconitim napellus has long been officinal as a narcotic and analgesic.

The fruit is poisonous, containing, amongst other substances, the alkaloids theobromine and caffeine, as well as an extremely bitter terpene. Poisonings are more common in young children, who are enticed by the brightly coloured fruits. Ingestion can result in liver and kidney damage and even death. It has proved fatal to sheep.

Poisonous

Daphne

Spurge-Laurel (Daphne laureola)

View photos in Wikimedia Commons

All parts of daphne contain toxins, but the greatest concentrations occur in the bark, sap, and berries, which are poisonous to humans. Even a single berry chewed but not swallowed typically causes intense burning in the throat and mouth. Consumption of a few berries can cause upset stomach, headaches, diarrhea, delirium, and convulsions. If the victim falls into a coma, death can ensue. The sap is known to cause skin rashes on contact, so wear gloves against this caustic sap.

Poisonous

Buttercup

Stinking Hellebore (Helleborus foetidus)
Green Hellebore (Helleborus viridis)

View photos in Wikimedia Commons

All the hellebores have a burning taste and are highly poisonous owing to the presence of the glycosides helleborin and helleborein. Both Helleborus viridis and Helleborus foetidus were formerly officinal as violent cathartics and emetics, but their use has long been discontinued.

Highly Poisonous

Nightshade

Thorn-Apple (Datura stramonium)

View photos in Wikimedia Commons

Tropane alkaloids are autonomic nervous system blocking agents. The level of alkaloids in individual plants varies from day to day depending on environmental conditions and stages of plant development. This can lead to problems for people who use the plant as a narcotic as higher levels of these alkaloids can cause death instead of the intended "trip." 
To learn more about these alkaloids and the toxicity of Datura check out "Medical Botany: Plants Affecting Man's Health" by Walter H. Lewis, P.F. Elvin-Lewis (A Wiley-Interscience publication) (Paperback)

Very Poisonous

Umbellifer

Tubular Water Dropwort (Oenanthe fistulosa)
Hemlock Water Dropwort (Oenanthe crocata)
Fine-Leaved Water Dropwort (Oenanthe aquatica)

View photos in Wikimedia Commons

The active poison is oenanthotoxin. The root is particularly dangerous, as it lacks the unpleasant flavour of the foliage, but is equally toxic: the species is common in wet ditches and streamsides, and the roots are often exposed when drainage ditches are cleared. Livestock fatalities are frequent when these exposed roots are found and eaten in mistake for parsnips, one root being sufficient to kill a cow. Human fatalities are also known in these circumstances.

Extremely Poisonous

X, Y, Z

 

 

Yew

Yew (Taxus baccata)

View photos in Wikimedia Commons

Most parts of the tree are toxic, except the bright red aril surrounding the seed, enabling ingestion and dispersal by birds. The major toxin is the alkaloid taxane. The foliage remains toxic even when wilted or dried. Horses have the lowest tolerance, with a lethal dose of 200–400 mg/kg body weight, but cattle, pigs, and other livestock are only slightly less vulnerable. Symptoms include staggering gait, muscle tremors, convulsions, collapse, difficulty breathing, coldness and eventually heart failure. However, death occurs so rapidly that many times the symptoms are missed. The wood remains poisonous after it is cut.

Fatal

General Poison Remedies from The New illustrated Gardening Encyopedia by Richard Sudell - Published in 1950:-

For most plant poisons it is safe, while waiting for doctor's arrival, to give:

  • A drink of milk, which coagulates in the stomach and may take up poison in its clot.
  • An emetic, which should bring away milk and poison together.
  • A purge, such as 1 fluid ounce (30 millilitres) of castor-oil, which should clear out any remainder of poison.
  • Some strong tea - preferably boiled, as tannin is an antidote to many poisons; or another stimulant such as brandy or sal volatile (smelling salts).

Throughout, keep the patient warm, quiet, and with plenty of fresh air.
If patient seems sleepy, keep him/her awake as some poisons induce a "sleep of death".

Emetics:-

  • A dessertspoonful of mustard in a tumbler of lukewarm water.
  • A tablespoonful of salt in a tumbler of luke-warm water.
  • For a child - A teaspoonful of ipecacuanha wine repeated twice at intervals of 15 minutes.

 

"On average, two gardeners a year die in the UK as a result of poisonous plants. There are poisonous plants lurking in almost every garden, dangerous to humans and animals alike. Those discussed in this blog are by no means exhaustive, but illustrate a range of concerns that should be foremost in the designer’s mind." from A Garden Designer's Guide to Poisonous Plants by Oxford College of Garden Design.

This list of poisonous plants is only meant to provide orientation. It is not exhaustive as knowledge of chemical composition is quite insufficient. The toxicity levels are:-

  • Slightly poisonous - These are given so that their poisonousness is not overestimated.
  • Poisonous
  • Very poisonous
  • Extremely poisonous - Their inclusion in your garden scheme should be carefully considered.

A large amount of these slightly poisonous species would have to be eaten to lead to strong symtoms. Many species in these 4 poison types have such a repulsive taste, that it is hardly imaginable that children would voluntarily eat more than a few berries. The slightly poisonous, poisonous and very poisonous will lead to diarrhoea, vomiting, dizziness or headaches if their plant parts are eaten.

Extremely poisonous will kill you if eaten. You should see a doctor in any case.

A Guide To The Poisonous Plants And Weed Seeds Of Canada And The Northern United States by Robert Boyd Thomson, H. B. Sifton. University of Toronto Press, Published 1922. The primary reason for this publication is the long-felt need of a text-book to accompany the course on poisonous plants which is given the students of the Ontario Veterinary College. This object has been kept constantly in mind. It has necessitated the preparation of a book at a price within the reach of every student, and yet one that contains in easily available form an up-to-date knowledge of our common poisonous plants, the characteristics by which they may be recognized, the symptoms produced by them and the remedial treatment required. It is hoped that the book will also prove useful to the veterinarian who is in practice, the farmer, the stockman and, to a more limited extent, the medical practitioner and the public generally.

Poisonous Plants of Pakistan by Abid Askari will be published in August 2010 about 158 poisonous plants. The author has collected, in one volume, information about the poisonous plants that can be found in Pakistan, which previously could only be found in scattered, specialized scientific papers. Detailed descriptions of the plants and how to avoid injury from them are accompanied by the authors own accurate illustrations which highlight the poisonous parts of each plant. There is also useful information on how to recognise the symptoms of poisoning and provide first aid.

The castor seed contains ricin, a toxic enzyme. Heating during the oil extraction process denatures and deactivates the enzyme. However, harvesting castor beans may not be without risk. Allergenic compounds found on the plant surface can cause permanent nerve damage, making the harvest of castor beans a human health risk. India, Brazil, and China are the major crop producers, and the workers suffer harmful side effects from working with these plants. I wonder if the outstanding benefits outweigh the collection cost by humans.

Rhododendron poniticum "All the rhododendrons grown here in the UK are poisonous to livestock, who have access to garden refuse, clippings and the growing evergreen shrub or hedge. They contain a neutral principle - andromedo-toxin - which is also present in azaleas and kalmias. Symptoms of poisoning are similar in all animals --salivation, distressing attempts to vomit. colic, slow and difficu1t breathlng, staggering gait, great debility and death from failure of respiration. Post-mortem examination revea1s the presence of the leaves in the stomach. There is little, if any, inflammation, the vomiting being caused by the action of the poison on the nerve endings in the stomaoh walls" from BPP. Eating its honey leads to Mad Honey Disease.

Senecio jacobaea is Ragwort, Ben Weed and Curley Doddies.
"As ragwort poisoning takes the form of a slow but certain destruction of a vital organ, the liver, recovery is impossible. Prevention of poisoning lies in control of the weed in pastures and in crops intended for hay or artificial drying. By the time any animal (dog, cat, sheep, horse, cattle, pig) dies of ragwort poisoning; the plant parts will have passed out of the stomach and bowels, and the poisonous alkaloids will not be found in the tissues in sufficient quantity to make a definite chemical diagnosis" from BPP.
Where I live, I am surrounded by livery stables, whose fields contain this poison. In some of these fields; the grass has mostly been eaten due to there being too many horses for too little pasture, leaving only this weed for the horses to eat. We in England have such a caring nature in displaying fields with pretty yellow flowers, which can kill grazing animals!

Nova Scotia Museum
The Poison Plant Patch

Poison Ivy, Monkshood, Buttercup, Destroying Angel are all examples of toxic plants or mushrooms that can cause vomiting, convulsions, diarrhea, heart failure, contact dermatitis or death.

The deadly beauty of common wildflowers of the Northeast is illustrated here, in addition to the medical symptoms of poisoning. Learn more about the alkaloids, resins, oils and toxic proteins found in house plants, annuals, perennials or native wildflowers. More than 50 plants, mushrooms and algae are included. Did you know that only a few microscopic algae are responsible for the closure of shellfish to harvesting seasonally?

The website contains but a sample of potential poison plants, not all known toxic plants are identified, nor are all known plant toxins included. It is not intended to replace medical consultation, but is intended as an introduction to the possibilities.

POISON CENTRE INFORMATION
in Canada and Continental United States.
Plant ingestion is a major cause of poisoning in children under the age of six. Children are not the only victims: adults, pets and even farm animals also suffer the consequences of toxic plant ingestion.
To prevent such accidents, everyone should be aware of the potential dangers of indoor and outdoor plants.

PLANT POISON GUIDE
A plant is poisonous (Toxic) if it causes chemical injury to a person who either touches or swallows it, or in rare cases, breathes its scent. Harmful substances (Toxins) in plants are commonly classified by their effects upon victims, or their chemical structure:-

 

Alcohol
Intoxication from imbibing beer, wine, or distilled liquor to the point of inebriation is one form of alcohol poisoning.
The breakdown of cabohydrates produces alcohol, although there are a few plants that produce toxic alcohols.
2 plants are found in Nova Scotia to contain toxic alcohols, water hemlock and white snakeroot (a rarely seen plant). Some consider the water hemlock to be the most poisonous plant of temperate North America.

Alkaloids

Alkaloids are nitrogen-bearing alkaline chemicals that originate in plants. They are derived from amino acids, the building blocks of proteins, which especially affect the nervous system. At least 40% of all plant families include plants that contain these compounds.

Continued in next column --->
 

Alkaloids

Many plants have different alkaloids present, each with a specific activity. Some alkaloids are useful medicines; others are harmful, even fatal. Most are bitter tasting. The liver, with the assistance of enzymes, processes the alkaloids that enter the body, rendering some harmless there, while making others more toxic.
One common alkaloid, which many of us seek daily, is caffeine.

Carcinogens and
co-carcinogens
A plant is identified as carcinogenic when it is shown to cause cancer in persons touching or eating it.
A plant is said to be co-carcinogenic when it causes cancer only in conjunction with some other substance. Roquefort and camembert cheese moulds, daphne, and poinsettias, for example, can cause cancer only if the victim eats them while taking certain prescription drugs.

Glycosides
Glycosides are toxins in which at least one sugar molecule is linked with oxygen to another compound, often nitrogen-based. They become harmful when the sugar molecule is stripped off, as in the process of digestion.

Hay Fever allergens

Some people develop sensitivities to the physical properties of some plants, especially seeds or pollen.
Pollen is produced by all flowering plants; it is essential to the fertilization of flowers. Some plants depend upon the wind to pollinate the flowers. Buoyant pollen grains, especially from trees and grasses, blow from plant to plant.
Not all wind-pollinated plants are toxic, but they tend to produce copious amounts of dust-like pollen.

Continued in next column --->

Hay Fever allergens

In susceptible people, this irritating pollen causes hay fever. Many plants cause hay fever—grasses, alders, poplars, birches, elms, and maples, to name a few. Not everyone reacts to all allergenic plants.
Hay fever results in influenza- or cold-like symptoms, with a definite seasonality to the condition. Spring sufferers of hay fever are probably allergic to tree pollen; early summer brings on reactions to grasses; and fall sufferers probably can’t tolerate ragweed.

Oxalates
Oxalates are unstable salts of oxalic acid. When eaten, they break down to release the highly poisonous acid.
The sour flavour of sorrel (Rumex species), wood sorrel (Oxalis), and even rhubarb is due to the presence of the acid.
Some plants may contain differing amounts of potassium or calcium salts, rendering them unsafe, particularly in the buckwheat and goosefoot families.

Phenols
Phenols are acidic compounds that can stop all functions of living cells by altering or binding proteins. The most notorious phenol plant poison in Nova Scotia is the irritant found in poison ivy and its relatives, but phenols are also found in nettles.

Phototoxins
Phototoxins are chemical substances that make the skin very sensitive to the ultraviolet radiation in sunlight and other light sources.

Proteins and Amino
Acids
Proteins and amino acids are complex chemicals necessary to all living cells; most are highly beneficial, not harmful. Chains of amino acids form proteins; if more than two are joined, they are called peptides, rings of amino acids joined together make cyclopeptides like amanitins, some of which are the most deadly poisons known.

Resins and Volatile
Oils
Resins and volatile oils are derived mostly from hydrocarbons—chemicals composed of hydrogen, carbon, and oxygen. This group of poisons is very diverse.

Shellfish Poisons
Shellfish poisoning occurs when filter-feeding shellfish (mussels, clams, oysters, and scallops) eat certain kinds of tiny marine algae. Toxins produced by the algae accumulate in the shellfish, making them poisonous when eaten.
In Nova Scotia, three main types of shellfish poisoning are known to occur: amnesic shellfish poisoning (ASP), diarrhetic shellfish poisoning (DSP), and paralytic shellfish poisoning (PSP). Generally, these are caused by marine algae called diatoms.

Pages 690-696 of The New Illustrated Gardening Encyclopedia by Richard Sudell, printed before May 1935 for the plant names, followed by details for culture and propagation. Those pages contain table with plant, poisonous part, name or character of poison with its Antidote or Remedies and notes.

Thornapple - Datura stramonium. Whole plant very deadly. Hyoscyamine - produces madness and death. A mustard emetic, then magnesia; flick face with wet towel, give sal volatile, black coffee, strong boiled tea or stimulants, and artificial respiration if coma intervenes.

General Poison Remedies
For most plant poisons it is safe, while waiting for doctor's arrival, to give:-

1. A drink of milk, which coagulates in the stomach and may take up poison in its clot.
2. An emetic, which should bring away milk and poison together.
3. A purge, such as 1-ounce of castor-oil, which should clear out any remainder of poison of the stomach through the mouth.
4. Some strong tea - preferably boiled, as tannin is an antidote to many poisons; or another stimulant such as brandy or sal volatile.
Throughout keep the patient warm, quiet, and with plenty of fresh air.
If patient seems sleepy, keep him awake as some poisons induce a "sleep of death". Specific remedies are given in this list for more virulent and rapid poisons, but as some of the antidotes are as fatal as the original poison, it is nececessary always to send for a doctor to prescribe the correct dose.

Emetics.
1. A dessertspoonful of mustard in a tumbler of lukewarm water.
2. A tablespoonful of salt in a tumbler of luke-warm water.

For a Child.
3. A teaspoonful of ipecacuanha wine repeated twice at intervals of 15 minutes.

Top ten plants that are bad for bees from Countryfile Magazine

"Lavender, alliums, fuschias, sweet peas - keen gardeners know the very best flowers to entice bees to their gardens. But what about plants that are  bad for bees? Here is our expert guide to the top ten plants that you should avoid to keep bees happy and buzzing, plus the perfect alternatives.

1. Rhododendron
Spectacular and beautiful, not many people know the common rhododendron hides a poisonous secret – its nectar is toxic to bees. It’s common practice for beekeepers to keep their hives closed until the flowering season is over. The resulting honey from rhododendrons has also been known to contaminate honey, making it unsafe for humans to eat.
Alternative: Clematis have beautiful, wide flowers and are 100 per cent bee-friendly.

2. Azalea
Rhododendron’s sister, azaleas are also toxic to bees.
Alternative: Foxgloves (Digitalis) are a bee favourite and despite being poisonous if consumed by humans, they are both honey and bee safe.

3. Trumpet flower, or angel’s trumpet (Brugmansia suaveolens)
Though ornamental and sweet smelling, the trumpet flower’s nectar can cause brood death in bees and is best avoided.
Alternative: Try honeysuckle (Lonicera) instead for deliciously scented results.

4. Oleander (Nerium oleander)
Harmful to butterflies as well as bees, oleander has a severe effect on hives. Nectar taken to the hive concentrates as it dries out, which increases the amount of toxins and usually results in a mass hive wipeout. 
Alternative: Snapdragons (Antirrhinum majus) are equally as bright and arguably more attractive in small or large gardens.

5. Yellow Jessamine (Gelsemium sempervirens)
Pleasantly aromatic and attractive as they are, bees are often poisoned by the vines and flowers of the yellow jessamine and its toxins are said to be as severe as hemlock.
Alternative: Plant Black-eyed Susans (Rudbeckia hirta) in tubs and along fences for a pretty, easy-to-grow substitute.

6. Mountain Laurel (Kalmia latifolia)
Part of the blueberry family, the mountain laurel is an evergreen shrub with sweet, white or pink flowers when in bloom. Pretty they may be, but the honey produced by mountain laurel is toxic to humans and is often bitter tasting.
Alternative: Lilacs (Syringa) are both beautiful and wonderfully sweet smelling. Easy to grow and are loved by bees and butterflies. 

7. Stargazer lily (Lilium 'Stargazer')
Stunning but deadly to cats, stargazer lilies’ pollen is poisonous to bees.
Alternative: Hollyhocks (Alcea) are impressive and just as beautiful as the stargazer but bee-friendly.

8. Heliconia Exotic and interesting, heliconia, or lobster-claws as its sometimes called, is very toxic to bees. You should not prune your heliconias, as the 'stem' is actually made up of rolled leaf bases and the flowers emerge from the top of these 'pseudostems'. However, each stem will only flower once, so after flowering you can cut that stem out. This is recommended, to encourage more flowering, to increase airflow in between the stems of your plant, and also to generally tidy it up and improve the appearance.
Alternative: Although not quite as exotic, hyacinths are fragrant, gorgeous and easy to grow. Hyacinth bulbs are poisonous; they contain oxalic acid. Handling hyacinth bulbs can cause mild skin irritation. Protective gloves are recommended.

9. Bog rosemary (Andromeda polifolia -
All parts of the plant contain andromedotoxin and are considered poisonous)
Not to be confused with the herb, bog rosemary is acutely poisonous and the honey produced from the nectar of Andromeda polifolia contains high enough levels of grayanotoxin to cause full body paralysis and potentially fatal breathing difficulties due to diaphragm paralysis.
Alternative: Why not try planting a classic rosemary bush (Rosmarinus officinalis) – aromatic, resilient and favoured by bees.

10. Amaryllis (Hippeastrum)
Now most commonly recognised as decorative Christmas flowers, amaryllis are gorgeous in bloom but their pollen produces toxic honey. Bulbs, chewing or ingestion of the bulbs, leaves or flowers poisons goats and sheep with Lycorine (An emetic) and small amounts of alkaloids.
Alternative: Dahlias are a highlight of late summer gardens. Beautiful and simple to grow, dahlias often flower until the first frosts of the year."

This is another list of Plants toxic to bees, which includes:-
Aesculus californica,
Angelica triqueta,
Asclepias species,
Astralagus species,
Astralagus lentiginosus,
Camellia thea,
Corynocarpus laevigata,
Astralagus miser v. serotibus,
Cuscuta species,
Cyrilla racemiflora,
Ochrama lagopus,
Solanum nigram,
Sophora microphylla,
Tillia species,
Veratrum cailfornicum,
Zygadenus cenesosus.

 

The following details come from Cactus Art:-

"A flower is the the complex sexual reproductive structure of Angiosperms, typically consisting of an axis bearing perianth parts, androecium (male) and gynoecium (female).    

Bisexual flower show four distinctive parts arranged in rings inside each other which are technically modified leaves: Sepal, petal, stamen & pistil. This flower is referred to as complete (with all four parts) and perfect (with "male" stamens and "female" pistil). The ovary ripens into a fruit and the ovules inside develop into seeds.

Incomplete flowers are lacking one or more of the four main parts. Imperfect (unisexual) flowers contain a pistil or stamens, but not both. The colourful parts of a flower and its scent attract pollinators and guide them to the nectary, usually at the base of the flower tube.

partsofaflowersmallest1

 

Androecium (male Parts or stamens)
It is made up of the filament and anther, it is the pollen producing part of the plant.
Anther This is the part of the stamen that produces and contains pollen. 
Filament This is the fine hair-like stalk that the anther sits on top of.
Pollen This is the dust-like male reproductive cell of flowering plants.

Gynoecium (female Parts or carpels or pistil)
 It is made up of the stigma, style, and ovary. Each pistil is constructed of one to many rolled leaflike structures.
Stigma
This is the part of the pistil  which receives the pollen grains and on which they germinate. 
Style
This is the long stalk that the stigma sits on top of ovary. 
Ovary
The part of the plant that contains the ovules. 
Ovule
The part of the ovary that becomes the seeds. 

Petal 
The colorful, often bright part of the flower (corolla). 
Sepal 
The parts that look like little green leaves that cover the outside of a flower bud (calix). 
(Undifferentiated "Perianth segment" that are not clearly differentiated into sepals and petals, take the names of tepals.)"

 

 

 

The following details come from Nectary Genomics:-

"NECTAR. Many flowering plants attract potential pollinators by offering a reward of floral nectar. The primary solutes found in most nectars are varying ratios of sucrose, glucose and fructose, which can range from as little a 8% (w/w) in some species to as high as 80% in others. This abundance of simple sugars has resulted in the general perception that nectar consists of little more than sugar-water; however, numerous studies indicate that it is actually a complex mixture of components. Additional compounds found in a variety of nectars include other sugars, all 20 standard amino acids, phenolics, alkaloids, flavonoids, terpenes, vitamins, organic acids, oils, free fatty acids, metal ions and proteins.

NECTARIES. An organ known as the floral nectary is responsible for producing the complex mixture of compounds found in nectar. Nectaries can occur in different areas of flowers, and often take on diverse forms in different species, even to the point of being used for taxonomic purposes. Nectaries undergo remarkable morphological and metabolic changes during the course of floral development. For example, it is known that pre-secretory nectaries in a number of species accumulate large amounts of starch, which is followed by a rapid degradation of amyloplast granules just prior to anthesis and nectar secretion. These sugars presumably serve as a source of nectar carbohydrate.

WHY STUDY NECTAR? Nearly one-third of all worldwide crops are dependent on animals to achieve efficient pollination. In addition, U.S. pollinator-dependent crops have been estimated to have an annual value of up to $15 billion. Many crop species are largely self-incompatible (not self-fertile) and rely almost entirely on animal pollinators to achieve full fecundity; poor pollinator visitation has been reported to reduce yields of certain species by up to 50%."

 

The following details about DOUBLE FLOWERS comes from Wikipedia:-

"Double-flowered" describes varieties of flowers with extra petals, often containing flowers within flowers. The double-flowered trait is often noted alongside the scientific name with the abbreviation fl. pl. (flore pleno, a Latin ablative form meaning "with full flower"). The first abnormality to be documented in flowers, double flowers are popular varieties of many commercial flower types, including roses, camellias and carnations. In some double-flowered varieties all of the reproductive organs are converted to petals — as a result, they are sexually sterile and must be propagated through cuttings. Many double-flowered plants have little wildlife value as access to the nectaries is typically blocked by the mutation.

 

There is further photographic, diagramatic and text about Double Flowers from an education department - dept.ca.uky.edu - in the University of Kentucky in America.

 

"Meet the plant hunter obsessed with double-flowering blooms" - an article from The Telegraph.

7. when I do not have my own or ones from mail-order nursery photos , then from March 2016, if you want to start from the uppermost design levels through to your choice of cultivated and wildflower plants to change your Plant Selection Process then use the following galleries:-

  • Create and input all plants known by Amateur Gardening inserted into their Sanders' Encyclopaedia from their edition published in 1960 (originally published by them in 1895) into these
    • Stage 1 - Garden Style Index Gallery,
      then
    • Stage 2 - Infill Plants Index Gallery being the only gallery from these 7 with photos (from Wikimedia Commons) ,
      then
    • Stage 3 - All Plants Index Gallery with each plant species in its own Plant Type Page followed by choice from Stage 4a, 4b, 4c and/or 4d REMEMBERING THE CONSTRAINTS ON THE SELECTION FROM THE CHOICES MADE IN STAGES 1 AND 2
    • Stage 4a - 12 Bloom Colours per Month Index Gallery,
    • Stage 4b - 12 Foliage Colours per Month Index Gallery with
    • Stage 4c - Cultivation, Position, Use Index Gallery and
    • Stage 4d - Shape, Form Index Gallery
    • Unfortunately, if you want to have 100's of choices on selection of plants from 1000's of 1200 pixels wide by up to 16,300 pixels in length webpages, which you can jump to from almost any of the pages in these 7 galleries above, you have to put up with those links to those choices being on
      • the left topic menu table,
      • the header of the middle data table and on
      • the page/index menu table on the right of every page of those galleries.

There are other pages on Plants which bloom in each month of the year in this website:-

 

 

Pruning

Pruning Made Easy - A gardener's Visual Guide to when and how to prune everything, from flowers to trees by Lewis Hill. Published by Storey Publishing as one of its Storey's Gardening Skills Illustrated Series in 1997.
ISBN 1-58017-007-2. Lewis Hill owned Berryhill Nursery.

The illustrations combined with the text tell you precisely what to do in the above book.

I have spent a long time investigating the state of the trees in pavements within Funchal in Madeira and I have taken 100's of photos to show what happens when any tree is pruned and allowed to rot followed by the inside rot being set light to. You can look at the welcome page, and below this leads on to the start page of the 100's of photos linked to in the comments on cavity repair, for further details.

Cavity repair.
"1. Clean out the cavity carefully. Remove all dirt, old bark, insects, and rotten wood right down to soil wood, much as a dentist cleans out a tooth prior to filling it, If possible, flush out the area with clean water." Fine.

"2. Smooth out the rough edges with a heavy-grit file" No, that would tend to remove the remains of the branch collar and further damage the tree.

"3. Fill the hole with a good tree-cavity sealer. Asphalt compounds, such as those used in patching driveways and roofs, are suitable..."
No, asphalt as well as concrete are solid and may shrink slightly as they dry out leaving a gap where the water, insects can get back in and rot the tree.

I suggest the following:-
"Solution to holes in trees.
Remove ... rot within the hole. Then blast the remaining rot with a high pressure water hose to try and clear more of the rot. Spray with Boron (a water based preservative kills only wood boring insects - not spiders, birds or bats) as a treatment for insect, wet and dry rot attack. While it is still wet, apply a layer of Expanding Foam to the bottom of the hole. Immediately place bottles on this and allow to set for 5 minutes. Apply another layer of expanding foam and another layer of bottles. The aim of the bottles is to occupy space, they are not there as a deterrent. That is why the foam has to be in contact with the inside of the tree not the glass bottle. The poisons in the foam will kill anything eating it and the foam does stick better when wet with water. Keep up this operation until the hole is covered. 
Leave to set and then paint the foam surface twice with a recommended water-based, but not oil-based, sealant.

Solutions to stop creating holes in trees.
When a branch is cut off, remember to cut it off on the other side of the Branch Collar. (See Figure 1 - Optimum position of the final pruning cut in "Guide to Tree Pruning" by the Arboricultural Association which shows the branch collar within and outside the tree. My Comments: I disagree with their recommendation not to apply wound paint as you can see the result if you do not paint trees which are dehydrated, starved and gassed as these trees in the pavements of Madeira are.) 
Once that is done, then immediately apply Boron and 2 coats of protective sealant as used for holes in trees above." from Photo Damage to Trees in Madeira Page 1.

I also saved the yew tree in my local churchyard.

Cutting grafting wood.

A solution for grass round trees depriving them of water and nutrients; using the expertise of DLF.
If the turf was uplifted during August/September using a fork for a distance of 24 inches (60 cms) round the base of the tree trunk in the grass and placed upside down beyond that 24 inches, that would expose the roots of that tree. 10 grammes of PM105 which is equal parts of Alsike White Clover, Red Clover, White Clover, Yellow Trefoil and Birdsfoot Trefoil could be added to a bucket, with 50 grammes of Rehofix MK1500 Bulking Granules (these are corn skin granules and biodegradable and used as a carrier for the PM105). This mixture could be mixed with 12 grammes of Groweb Tackifier (a gelling agent that when mixed with water, swells becoming highly viscous, binding the seed and the Rehofix and sand to the soil surface. It also stops anybody else from taking the seeds, whether it is wind, bird, or human). This is then distributed onto the exposed soil between the trunk and the water ring created by the overturned turf slabs. Then 2 bags of sharp sand are spread over the sown seed to prevent birds from eating the seeds and to cover the exposed roots of the tree. This is followed by spraying 2 gallons of water on top of the sand, and the wildflower seeds can then grow through the sand with the clover. The clover are legumes and would fertilise the tree roots. Since there is usually quite a bit of rain from October to March, irrigation of these wildflowers would be unnecessary and having grown during that autumn/winter period, these plants would probably be okay for the following spring/summer growing conditions. The replacement of the turf with these wildflowers would stop that area of turf from drinking all the rain that falls on it and if any fertiliser was applied on top of it, from it using all of it and the tree getting none.
