Rainwater Drainage Are you aware of the legislation that came into force on 1st October 2008 which affects the drainage of front drives? www.communities.gov.uk/ publications/planningandbuilding/ pavingfrontgardens gives government advice on driveway planning which you may find useful. Apparently; after talking to a contractor in March 2018, the contractor and the householder will be fined £2000 each if that driveway does allow rainwater onto a public area. If you understand his attempt to provide a soakaway, then he creates a 1 cubic metre soakaway irrespective of what the soil is underneath the drive. You have to allow for a 2 inch (5 cm) depth of rain over the drive, so that 1 cubic metre soakaway will only allow for 20 square metres. When I have seen new driveways, which slope downwards to the pavement, I have seen a drain on the bottom edge before the pavement, but I have not noticed a soakaway. A drain may only contain a few litres and then the rest will go onto the pavement and the road. Hopefully the others which slope down towards the house do not have their drains going into the main drain from the house or the public storm sewer. Front drives larger than 5 square metres are no longer allowed to discharge water onto the public road or into the domestic drainage without planning permission. If you don't want to apply for planning permission at a cost of £150, the drive must be constructed of porous paving or a system such as channel and drain used to catch all surface flow and discharge it to a soak away (See Video from Marshalls on How to Install Driveways - Block Paving Installation) or other SUDS compliant facility on your own site. Point to note on Video from Marshalls, where they constructed a soakaway on site:-
If you construct any paving that directs the rainwater off your site, then this could delay or even stop a house sale - see Interpave for the latest information. Why am I harping on about drainage on drives - the rainwater you allow onto the road will either go into a stormdrain or go to the bottom of the hill and could flood your neighbours down there, or the road down there. The stormdrain is designed for use by the public areas like pavements and roads, and not for the rainwater from your property as well. Nor is the Main Drain from your house designed for that rainwater either. Only the roof drains may connect to the public storm sewer. . |

The following drive collected all the water and drained it to climbing roses alongside the drive. Even though the subsoil is clay, there has been no complaints of the system getting overloaded during the last 16 years. CEDAdrive® provides an excellent low maintenance SUDS compliant surface suitable for paths, drives, car parks, caravan sites and lorry parks. CEDAdrivel® has been through extensive research and development to bring you the very best gravel stabilisation system on the market. The large sheets of 2.15m x 1.14m x 40mm are fitted with a geotextile underside and has been tested to 300 tonne when filled, which makes Cedagravel® extremely tough and very quick and easy to install. Further details at bottom of this page.
I have used this product for paths, driveways and patios. In order to provide a patio without losing a section of lawn, I have laid Plantex with CEDAdrive on top, filled it with loose earth, watered it, spread grass seed, filled again with earth and watered it. It then became a lawn that outside chairs and tables could be laid on without deforming this new lawn. . |

Drive Foundations If the foundation for a drive is incorrect, then vehicular access can deform it. If there is no foundation under a pedestrian path or patio, the surfacing layer can be raised/lowered by the weather. Spon's Landscape Handbook provides an overview for those involved in landscape planning, design, construction and management:- The layers of material that make up a full-scale road are:-
|
|||||||||||||||||||||||||
SubstrateWhen dealing with sub-bases, the soil (substrate) can be divided into 6 types and 2 categories depending on the level of the water-table. Each type and category is given a California Bearing Ratio percentage number (CBR). A geotextile (like Plantex) filter membrane should be laid between the substrate and the sub-base. See below this plan and photos for remainder of this technical note.

Concrete and rainwater soakaway trench excavated. Weatherboarded fence removed. |
The perforated drainage pipe was surrounded by 8mm peashingle (supplied by Allsand Supplies Ltd), which was enveloped in Plantex (Plantex is a geotextile used to separate materials from combining with each other and is available from Travis Perkins builders merchants). 6 Gully covers with chamber risers filled with planting compost were placed on top of this drainage pipe, so that the climbing roses inserted in that compost would have a water supply from below. |
Clay excavated. Perforated Drainage pipe installed in trench with 1:40 fall from garage to drive entrance.
|
|||||||||||||||||||||||
Concrete edging and foundation was installed |
Concrete edging was installed to stop the sand from migrating. It was haunched with concrete on each side for strength. 6" deep of Type I Roadstone was placed on top of Plantex as foundation. The fence was created and installed by Jacksons Fine Fencing to my specification. I installed the gree plastic coated chainlink fence to provide a climber support system for the Zephirin Druin thornless climbing roses. |
Zephirin Druin climbing rose installed in planting compost and mulched with peashingle. |

Sub-base
A granular sub-base as used for this drive (and I use under paths and patios as well) consists of aggregate to the specification of DOT Type I (Department of Transport). I use the crushed rock alternative, which must pass a 75mm sieve, and be free from dust or any pollutant such as oil or other chemicals. The thickness of the sub-base is determined by using the California Bearing Ratio percentage number (CBR) from the table below in the Estimated sub-base Thickness Table. |

I used a 150mm (6 inch) thick sub-base for average clay conditions, then 50mm (2 inches) thick of compacted sharp washed sand complying with Table 2 of BS 6717 Part 2 (BS is British Standard) followed by laying 60mm thick concrete pavers on top. These were then vibrated down with 6 bags of dry paving sand to lock the pavers together. |
|||||||||||||||||||||||||
Construction Notes:- These materials had to be excavated by hand and removed by wheelbarrow due to the clay main drain 6" below the concrete surface, with brick manhole walls, lead mains water pipe alongside the house wall and yellow gas pipe across the drive and 1 foot below and no access allowed from next door's drive. Instead of using 10" wide joists as a skip ramp, I would recomend the use of Load-Eze for safety reasons . |

CEDAdrive Stabilisation System from CED Natural Stone The Stability of Paving with the Versatility of Gravel for the following benefits:-
and the following properties:-
Installation Guide written by CED Preparation As with all other types of paving start with a good foundation. If your application calls for vehicular access lay a sub-base of compacted MOT type 1 (or possibly hardcore) to 100mm-150mm in depth and cover it with a layer of 20-40mm deep layer of sharp sand. This must be compacted and flat before the sheets are laid.
Paths and pedestrian areas can be laid on top of compacted sharp sand without a sub-base, again approximately 20mm-40mm in depth, again compacted and flat. Laying Place the honeycomb sheets over the prepared ground.
Edging The edge of the honeycomb area needs to be retained. This can be done using existing walls and buildings, stone setts, kerbs, timber, metal edging systems etc. The edging needs to be laid so that it is proud of the finished gravel level by at least 20mm. Gravel
Important note: Avoid heavy loads on the unfilled honeycomb during installation. CED LTD, 728 London Road, West Thurrock, Grays, Essex. RM20 3LU

When it rains, then the water drains through the cedargravel into the sand/hardcore underneath instead of draining onto the pavement and thence to the road. That extra water would if allowed to drain onto that public road possibly cause flooding of that road or other people's property further down the road. Because the pea-shingle fills separate containers, it is possible with careful placement to create either a Hopscotch playing area or a layout for Snakes and Ladders. The Hopscotch can also be used by us geriatrics for exercise periods and the Snakes and Ladders for slower walking exercise, instead of only children playing the respective game!! |

When you calculate the amount of rain water that you are required to take and put into a soakaway, it is 2 inches (5 cms) over the entire surface area of the roof. You need to do the same calculation for your drive and that is a great deal of water. It is best to adopt the french drain principle detailed above to try and make sure that if you do not use a CEDAdrive system on non-clay soil, then if you do what an amazing number of so-called professionals do which is to put pavers with no plastic cross-paving spacer between the pavers to allow for rainwater drainage between the pavers and only an open drain covered with a grill from side to side of the drive at the juncture of the drive with the public pavement outside. This open drain does not actually go to a soakaway on the owner's property, so when it rains the rainwater ends up on the street to the detriment of the people who live below their property who may be flooded; together with the overloading of the public sewers, and this is illegal. If you are on clay, you must not put the rainwater down into your main drain, but follow what I have stated at the top of this page. If you dig a hole about 2 spades depth and fill it full of water and it has not completely drained within an hour, then your soil has a proportion of clay in it. |

Having got your drive foundation down, the final expense on this amended drive is sowing grass seed If sowing grass seed is not up your street, why not pay a firm to install an inch depth of sharp washed sand and then washed turf on top of that and then water it for you for the required period to get the roots into the sand/foundation and be able to sustain itself. QED:-
This is a photo of a Ryegrass plant, that was growing in Type I MOT Roadstone on flat ground in a private garden. You will note that it has a great deal of fibrous root - apparently in American Baseball Stadiums each grass plant has over 100 miles of root. |
|||||||||||||||||||||||||
. That root in cooperation with worms, bacteria etc takes in food, which is brought down from the surface by water (usually rain, but can be by irrigation) either in tunnels created by the worms, moles, etc or when the ground cracks open in the summer when the clay soil dries up and shrinks - clay soil can absorb 40% of its own volume before it turns from a solid to a liquid. That root also breathes in oxygen then expels carbon dioxide (Click on Carbon Cycle) and nitrogen (Click on Nitrogen Cycle) ALL THE TIME. If you buy Sharp-Washed-Sand from a Builder's Merchant and put that into a clean pot round a plant, then using NPK fertilisers the roots of that plant can absorb that food dissolved in water. Once you stop supplying that water and food, that plant will die (it is like saying that for you to survive, that you need a lb of glucose each day, so I sit you down outside and put 365 lbs of glucose round your feet. It rains and within 6 weeks that glucose has either been eaten by you or dissolved in the rain and washed down into the ground below your feet. Then you complain to me that you are hungry). To make that Sharp-Washed-Sand into soil, you need dead plant material, shit from animals or dead animals, bacteria, worms that can be eaten by the animal, bacteria and worms to bind those sand particles together with clay and organic matter (Click on Soil Structure). That soil can then hold onto the some of the rain (Click on How does Water act in the Soil) with food for the animal/plant in it, before the excess rain drains through below the top soil to the sub-soil and the food in it is then lost to the plants above it. The easiest method of supplying the dead plant material is to collect your potato peelings, tea bags, coffee grounds in a bucket under the sink before putting them on the ground surface round a plant. Then, mow the lawn and put 1cm or 0.5 inch depth of grass mowings on top to complete the organic mulch, provide water from the grass and nitrogen from it to compost the peelings below. The worms having made tunnels in the soil may also eat the peelings. When it rains the water can absorb nutrients from that mulch and take it down using those tunnels. WHEN THOSE TUNNELS ARE FULL OF WATER AND A CLOD-HOPPING HUMAN WALKS ON IT, THEN IT COLLAPSES AND NO LONGER FUNCTIONS. If it rains heavily, allow the ground to recover for a couple of days before walking on it. You can then see that a Sandy Soil is much easier for the roots of a plant to get into, but when it rains it dries up quickly and then the food in it gets washed through it very quickly (Click on How are Chemicals stored and released from Soil?). It is also easier for the gases to get in and out. A clay soil is more difficult for plants, since when it rains the tunnels fill up with water and thus could drown the roots. Put sand round its roots up to the surface of the soil and this will combine with the clay to stop the roots from being drowned or without Nitrogen and Carbon gas exchange. If your lawn is soggy when it rains, then cut the lawn short when it is dry and apply 25Kg of sand over a 5 metre x 5 metre area once a month for 3 months during May-September and it will change the soil structure to lessen that. A mixture of Clay and Soil is best (Click on Soil Formation - What is Soil Texture?).
I saw a yew tree that had been planted in a churchyard in 2000 as a 2 foot high tree. In 2009 it had reached 7 feet high and 3 feet across. Why had it not grown? It was planted on a 30 degree slope in clay/sand soil with grass growing round its base. It had the following 3 reasons for failure to grow:-
So, I carefully removed the grass and its roots from around its base out to the tips of the tree branches and mulched that bare ground with shrub prunings / grass mowings to a 4 inch depth. A year later it was growing quite well with new leaves and an increase of density of branches. In Maderia I saw a mature olive tree - which had been transplanted from the nursery to a roof garden - a year after it was planted. It was on a mound with brazilian grass growing round its base. It was dying from dehydration even though it was irrigated every other day - the grass was growing well. An organic mulch about 4 inches deep on weeded soil makes garden maintenance very easy. Once a week you walk round the garden and using a swoe (a hoe has 2 arms to the horizontal blade, a swoe only has 1 so that you can stand on the lawn and be able to hoe behind the plant in front of you) hoe through the weed root in the top of the mulch and remove the uprooted weed. I find that Spent Mushroom Compost is light, easy to lay, easy to hoe and lasts a relatively long time. You may lose about 50% each year. If you do not apply any mulch and you do have groundcover plants covering all the soil, then you will enjoy permanent weeding chores like the painters on the Forth Bridge last century - you come to the other side and have to start again immediately. When you prune your shrubs/trees/hedges then put the prunings on your uncut lawn. When you deadhead your bulbs or remove perennials, shake off the earth from the roots and place on the uncut lawn. Using a rotary mower cut your lawn and it will cut the grass and your prunings/perennials into small bits which you then mulch your flower beds/hedges with. In the autumn, set your mower to its highest cut and transfer the autumn fallen leaves onto the lawn before mowing them and mulching as before. Continue mowing once a week untill all fallen leaves have been removed. If your garden is on a steep slope - I maintained one that had half-circle beds with lawn paths round them - the diameter of the circle was usually level and the half-circumference went down the slope. The ground had flint and chalk in it and the plants in it were usually the inverted cone shape. When it rained, the stones would be washed off onto the lawn paths and damage my mowing machine. Providing any mulch applied to those beds is covered with grass mowings, then that problem - of the stones being washed off by any rain however hard onto the paths - is stopped. Roots of plants that you put into your garden do extend and grow, but the existing roots do not move by themselves to better places. You have to untangle them and spread them out yourself. I planted a blue cedar in my front garden and 9 years later it died. When I took it out, I found that the roots which had been going round the inside of the pot before I planted it had expanded sideways to fill the complete space between them as if they were still in the pot. There were very few roots which had grown away from this rootball and so the plant died due to dehydration, lack of food and lack of gas exchange in the ground. A minor point that people forget is that you only live because you can breath oxygen, and plants provide it. So please look after the plant so that they have food, water and air (best soil has at least 30% air in it) on a regular basis, just like you do for your children. . |

The following photos show that nature can create conditions in and on a bed of Type I Roadstone - laid on a geotextile to prevent the soil under it from mixing with it - to support plants and then grow grass. This is the same garden as the one showing the roots of a Ryegrass plant above. The Roadstone had been laid to create a more level garden and then only used with a normal washing line to dry washing. The weeds were growing quite tall in the area where the dead leaves from the Leylandii Hedge growing alongside the boundary fence in the next door garden were depositing themselves. In order to reduce the length of time maintaining this garden, reduce the height of growing vegetation and since some grass had already started to grow, it was decided to sow grass seed and then let nature take its course without an irrigation system. |
|||||||||||||||||||||||||
So the first area was cleared, cheap grass seed sown and some sand was scattered over the seed to level the surface, prevent the birds from eating the seed and produce an easier area for the grass roots. The juvenile grass appeared after a couple of weeks. The weeds grow in the roadstone covering this garden and have been used as a mulch on the raised bed on the left. A self-sown seedling of an oak tree has been growing in this raised bed and its only maintenance consists of providing a mulch of the weeds removed from this garden round its base. Since this minimal maintenance program was started, the sapling has grown 4 feet in 2 years. The paver in the middle covers the hole for the supporting tube of the washing line. |
|||||||||||||||||||||||||
These show the new grass growing in the roadstone with sand on top and in the roadstone without sand on the top. |
So, if you want a new drive that will provide you with:-
then remember to use a geotextile under 4 inch depth (10cms) for sand or chalk soil or 8 inch depth for clay soil (Click on Case 3 which details the foundation depth required) to prevent the soil and stone mixing and the roots of trees or shrubs from growing in it. Then, sow your grass seed before blinding it with a thin layer of sharp-washed sand to level it and stop the birds from eating that seed. Then, from March to December mow it after each 3 week period to 1 inch (2.5cms) height to keep it low. |

According to the Civil Service Motoring Association Magazine of September 2012, "there are 7,000,000 UK gardens that have been paved over to make space for parking, says the RAC Foundation. The increase in vehicle numbers, and limit on public parking spaces, means that, of the 80 per cent of dwellings built with a front garden, two-thirds are now paved over for cars." Most of the current population in the UK breathe, and that means that most of the current population do not have the 25 x 25 feet of lawn necessary for that lawn to produce their required Oxygen for the year for them to breathe as well as the incredible amount of oxygen used by car engines. This means that the human population is currently asphyxiating itself, instead of growing grass to park their cars on. |

Soils and their Treatment Soil Improvement |

Road Noise, Airport Noise, Industrial Units and Railway Noise next to gardens is detrimental to humans living in those houses within those gardens. There are 4 methods commonly used for sound attenuation (the reduction of intensity of outdoor sounds before they reach the receiver) :-
If the house owner has a noise problem from outside their property, then they can use the same solution as above using 1, 2, 3 and 4 only. Their sheds and storage facilities can be installed in area 4 with path 3. leading to them.
There is also the problem of sound transmission between detached houses and between adjoining rooms in semi-detached or attached single-unit housing houses:-
Then, the combination of the above outside and this inside sound insulation could bring peace and utter contentment within!! |

Then, they could follow my following Suggested Action Plan for Builders after they have built their houses:-
And finally on the same day pour a depth of 11 inches (27.5 cms) depth of the builders soil mixture detailed below onto the remainder of the new garden areas and alongside the Instant Hedging.
A fortnight later the following type of turf containing RTF (Rhizomatous Tall Fescue), bred by Barenbrug Research USA, could be laid over the proposed lawn areas. The roots of that grass will reach the clay below and stabilise the new builders soil mix, before the proposed owners view the property a month later. The builders soil mix should within 3 months become roughly the same proportion of clay, silt and sand which is within a Sandy Clay Loam to create a sweet spot for growing plants as shown on How is material lost from the soil? Page, since it will mix with the clay below.

Design Cases When designing a garden, it is vital to know who and for how long the resulting designed and landscaped garden is going to be maintained by. The book 'The One Hour Garden' describes what maintenance work can be done in the time that you have allotted; and therefore what besides a lawn, you can have in your garden. My redesign and construction work to be done on my 3 gardens - as shown by Case 2 - must be to reduce the maintenance time required to the time I have available. If the gardens are first weeded, pruned, mulched, mown and bare earth converted to lawns using grass seed, then construction can take place in the future - as free time allows during a week or fortnight after the maintenance has been done. In Case 4, the combination of the Structural and Planting Designs would create a garden that I would be able to maintain in one day a fortnight. I would install a 3" deep mulch in the spring on the beds, so that I can prune the shrubs/trees and hoe the odd weed; whilst the father mows the lawns, the mother tends the vegetable garden and their teenage daughters play football!! The children in Case 5 loved to look at creepy-crawlies and wildlife, so that together with low-cost the design for different areas in a terrace house garden was created.
Construction Cases Case 3 is building a drive on clay and it is important to get the part you will not see - the foundations - done correctly. Case 8 is creating a pond with its pitfalls for foundations.
Maintenance Cases If you are asking someone to maintain your garden, then do provide the complete picture. If as in Case 1, you intend to sell the property, then look at this - as not a maintenance but as a selling job - and get that job done instead. Case 6 is creating a vegetable garden in a back garden during the maintenance program of one day a fortnight to maintain it and the remainder of the back and front gardens. This was done over 7 years using a crop rotation system Concrete ponds are likely to crack open due to movement in the ground levels due to being in clay or vibration caused by road traffic if it is fairly close. Case 7 shows no planting shelves for the pond plants. |

Problems for Houseowners and Builders when the new home is surrounded clay and how to solve them. 8 problems caused by clay:-
|
||
Builders do sell the original topsoil including
where the new building and its garden areas are to be built. The consolidated parent material (bedrock) is usually sand, chalk or clay with flint possibly. At the end of building; the builders rubble is covered with possibly only a 2 inch (5 cms) depth of imported topsoil, which might be the washings from the sugar beet in the sugar industry. This is covered with turf and the unsuspecting public is offered the result. As likely as not one of their gardens slopes towards the house and even with the modern depth of foundation wall, there is no guarantee that subsidence will not occur.
If every garden of a new house had a 12 inch depth of soil removed from its new garden area, then at the end of the building work, the Aquadyne Drainage System would be laid round the entire boundary. Next to it then plant the relevant Instant Hedge on the non-house wall sides to absorb the rainwater collected by that drainage system The mix to change clay soil into a friable useful soil in less than 4 months for the above domestic garden problem was in royal blue colour typing. Using the burgundy colour typing components, the builder could create the following soil mix for his gardens:
If water with 150 kgs of clay was first added to the Concrete TruckMixer and then the required volume of cullet followed by the required volume of waste plasterboard, the mixture is then mixed for an hour. If the cullet/waste plasterboard mixture is passed through the poultry houses to mix with the poultry litter on the litter floor before being collected into the next Concrete TruckMixer, then the houses would be cleaner and smell less. The required volume of waste from beer making could replace the Peat above and the requisite Sulphate of Iron and Sulphate of Potash could be added to the Concrete TruckMixer before that mixture from the Poultry Farm litter floor is added. That soil mixture could then be mixed for 30 minutes before applying it to the garden areas of the new houses built by the builder to an 11 inch (27.5 cms) depth. The resulting mixture would then integrate with the clay and create a deep topsoil within 3 months. All the requirements for a soil as shown in the figure above would then have mixed together and time will increase the bacteria and get a new soil structure created. The following type of turf could then be laid over the proposed lawn areas a fortnight later:- RTF (Rhizomatous Tall Fescue), bred by Barenbrug Research USA, produces rhizomes (an underground stem) that send a shoot up to the soil surface while extending new roots downwards. In fact, RTF can root to 1.5 metres deep giving it a chance to tap into water reserves that normal lawn turf cannot reach. |

|
There is other compostable waste that could be used in the above mixture - The following is from a farmer who runs Riverford Organic Farmers who deliver weekly boxes of vegetables, meat etc from their farms to the homes of members of the public in Britain in his weekly epistle dated Monday 4th December 2017:- |
|
"So why now, in my 57th year, have I seen the light?
So, I have seen the errors of my youth and come inside. Milan tells me we have only just started. It is shocking how much compostable material is wasted at such cost to our environment:
The reasons are:-
Time is running out; we cannot afford 100% safety when environmental destruction is 95% certain if we continue on our current path."
If the above waste was turned into compost that would last as a mulch like spent mushroom compost, which lasts for 2-3 years with 25-35% loss replenishment each year in the autumn, then it could be sold to the above home owners in bags to put alongside their hedges, in planted pots and in the flower beds throughout the year.
If you cannot be bothered to buy the commercially produced soil conditioner and collect your own seaweed to be harvested from beaches, then the following could still provide these other benefits in the same time slots as in above paragraph:- |

Section below provides details about flowers |
|
|
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. Androecium (male Parts or stamens) 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 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 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.
