Comment |
Clump-forming form. Use as ground cover between shrubs, robust perennials or light woodland. Pruning Group 14. "The Lamium genus includes both annual and perennial species; they spread by both seeds and stems rooting as they grow along the ground. The common name refers to their superficial resemblance to the unrelated stinging nettles, but unlike those, they do not have stinging hairs and so are harmless or apparently "dead". Lamiums are frost hardy and grow well in most soils. Flower colour determines planting season and light requirement: white- and purple-coloured flowered species are planted in spring and prefer full sun. The yellow-flowered ones are planted in fall (autumn) and prefer shade. They often have invasive habits and need plenty of room." from Wikipedia. "A handsome Dead Nettle. 61 cm stems carry pairs of dark, pointed, strongly-veined leaves. Beneath each pair is a whorl of rich strawberry-pink lipped flowers." from The Beth Chatto Gardens . This and other cultivars are available from The Beth Chatto Gardens and Hardy's Plants in the UK with Plant Lust in America. |

Ramblers Scramblers & Twiners by Michael Jefferson-Brown (ISBN 0 - 7153 - 0942 - 0) describes how to choose, plant and nurture over 500 high-performance climbing plants and wall shrubs, so that more can be made of your garden if you think not just laterally on the ground but use the vertical support structures including the house as well. The Gardener's Illustrated Encyclopedia of Climbers & Wall Shrubs - A Guide to more than 2000 varieties including Roses, Clematis and Fruit Trees by Brian Davis. (ISBN 0-670-82929-3) provides the lists for 'Choosing the right Shrub or Climber' together with Average Height and Spread after 5 years, 10 years and 20 years. |

Diascia Photo Album - this site is no longer available and the last update was on 8 February 2001 (this info was found on 2 March 2021). "I hope these pictures will help you identify the diascia you have. They are sometimes close-ups, sometimes long shots and most are scanned from photos or slides. They have been taken by my brother William or me unless otherwise credited. I aim to give a botanical description based on the writings of Hilliard & Burtt and Dr Kim Steiner in time." from Christine Boulby. |

|
Diascia 'Christabel' |
Bred by Hector Harrison. Has huge pale pink flowers in profusion all summer long. |
Diascia 'Coral Belle' |
Bred by Hector Harrison and Protected by Plant Breeders Rights. The only coral coloured diascia in distribution. Orangy-red flowers atop rich deep green foliage. Looks good in hanging baskets. |
Can be distinguished from other species by two distinct separate yellow windows in the throat of the flower. |
|
Diascia 'Doreen' |
Deep reddish purple flowers and a very prostrate habit. Found in my garden two years ago and named for my mum. |
Diascia 'Eclat' |
Seen here juxaposed against a penstemon. Lovely big red flowers. Not as long flowering as some other species |

|
Diascia fetcaniensis growing through a join in a retaining wall at Cragside, Rothbury |
This picture included to show the determination of this species. Its stolons will penetrate the tiniest cracks and roam up to three feet. |
Diascia 'Harry' |
Bred by Christine Boulby and named for my husband and best friend, Harry. Lime green foliage and reddish flowers. Bushy habit. |
This plant was one of Hector's first crosses and is named for him. He had had it in his garden several years before we were shown it, so it has stood the test of time. Bushy habit. |
|
Diascia 'Helvellyn' |
Pale pink flowers on nice shiny green foliage. Found by William in a garden in Barmby Moor at a house called 'Helvellyn'. |
Bred by Hector Harrison using D. integerrima 'Blush' and other plants. Has a nice neat bushy habit and lovely white flowers. |
|
|
|
White form of Diascia integerrima. Best grown in the garden where it will populate a large area over two to three years. Flowers later in the season (July/August here). Will tolerate the driest of dry places and has survived temperatures as low as -10C here in Northumberland. |

Origin unknown. Pale baby pink flowers atop dark green foliage. Neat habit. |
Bred by Hector Harrison and protected by Plant Breeders Rights. One of the reddest flowered diascias around, and on some of the deepest green foliage it is a stunner. Survives a good deal of dryness, and ideal for baskets. |
|
Distinguished from other species by a yellow 'median keel' of glands on the lower lobe of the flower. This photo shows its with Cistus ladanifer. A lovely combination. |
|
Diascia rigescens 'Anne Rennie' |
Similar to above but flowers a slightly paler shade and carried in rather more loose racemes. |
Diascia rigescens x lilacina |
One of Hector's earliest crosses and given to Blooms of Bressingham. Nice mauve flowers and good foliage. Prostrate habit. Good in baskets but its a bit of a thug |
Bred by John Kelly and introduced in 1971. Although he gave details of the cross he made to create it, we are not sure of the species he actually had due to name problems.It has nice blousy flowers on prostrate foliage and has been used in alpine beds for many years in the UK. |
|
Bred by Rupert Lambert. Plant has upright habit and reddish flowers. |
|
Bred by Hector Harrison. When i first saw it I was at Beth Chatto's gardens in Cambridgeshire. One of the first apricot coloured diascias to appear on the market in the UK and has been popular ever since. |

"Their common name is twinspur, in reference to the two (usually downward-pointing) spurs to be found on the back of the flower. These help to distinguish them from the similar (and closely related) genera Alonsoa and Nemesia. The spurs contain a special oil, which is collected in the wild by certain species of bees that appear to have coevolved with the plants, as they have unusually long forelegs for collecting the oil.
"Diascias are sun-loving plants, but enjoy fertile rather than dry, poor soil. The cushion-forming types can get straggly so cut them back in late April and late August to keep them compact.
"Diascia is a natural for containers. You can fill an entire container with one variety or use a diascia plant as your spiller, in a mixed container. Diascia also makes a lovely edging plant and will elegantly flop over sidewalks and walls or throughout rock gardens. |
|
Deer's primary defense is their sense of smell. When a garden has a lot of highly scented plants, the deer have trouble smelling predators and they realize that they are more defenseless. So use lots of fragrant herbs especially larger ones like Perovskia - Russian Sage and Nepetas that release their strong scent if the deer brush against them. Also, Deer do not like grazing extremely low, or too high. Shrubs and trees with foliage 3-5 feet or higher will be less likely to have deer damage." |
|
"Diascias often have a spreading, suckering habit. Their upright or sprawling stems are lined with pairs of small, toothed leaves, varying from heart-shaped to thread-like. The slender stems are topped with clusters of open-centred, five-lobed flowers 1.5-2cm across, with two backward-pointing spurs — and because of this, Diascia is also known as twinspur. At the base of the upper two lobes are two yellow windows, often almost merging into one. Diascia is often confused with Nemesia, which can be distinguished by having just one spur. The flowers of most species come in shades of rose-pink, but the cultivars now available encompass lilacs, deep reds, salmons, oranges and white. The long flowering season is one of the main attractions of diascias. Plants rarely set seed in the UK because of the climate and the lack of suitable insect pollinators, and this helps to prolong flowering. Young, vigorous plants produce the best displays. When flowering ceases, most diascias can be encouraged to flower again if trimmed back and given extra fertiliser and water. Diascias grow well in semi-shade but flower better in full sun. In well-drained soil, they will survive several degrees of frost, although plants often look miserable in cold weather. They vary in their hardiness. D. barberae, D. fetcaniensis and D. integerrima Award of Garden Merit (AGM) seem to be the hardiest of the species, with D. ‘Appleby Apricot’, D. ‘Ice Cracker’ and D. barberae ‘Ruby Field’ AGM considered the hardiest cultivars. When diascias first became popular, beginning with the appearance of ‘Ruby Field’ in the 1970s, they were viewed as perennials on the borderline of hardiness. Now it is mainly as plants for containers that their popularity has grown, with series such as Sun Chimes, Wink and Whisper introduced specifically for hanging baskets. The neater forms are also ideal at the front of borders and trailing types look good billowing over a low retaining wall.
New cultivars are introduced every year and these increasingly tend to have flowers close to the mat of foliage rather than held on upright stems high above the leaves.
Things to watch out for include aphids, which may infest young shoots. Slugs and snails can also be a problem and — if the conditions are poor — diascias can be susceptible to Botrytis. What the specialists say Christine Boulby, Diascia National Collection Holder, Northumberland “These are such charming plants and people do tend to fall in love with them easily. Some are perennials that tend to get cut short by our winters, even mild ones, so you would think they were annuals. “To succeed with diascias you should give them a sandy, free-draining soil, which is exactly the sort of conditions they endure in their native South Africa. “Our National Collection, although in Northumberland, is only a mile from the coast so we do not get too many frosts. This suits Diascia very well, and we suffer relatively few winter losses. “The plants have been marketed by the trade over the past decade or so as ‘patio’ plants, and so you will mostly see them growing as annuals in pots and hanging baskets. In a border situation, however, they can be very impressive plants, especially if they are allowed to spread their stems in between and through neighbouring shrubs. “‘Ruby Field’ is an excellent form and is special as it was one of the originals. D. integerrima Award of Garden Merit (AGM) is a hardy, wiry plant, with pink flowers from June to October, requiring little attention. Another excellent form is D. rigescens AGM. Although it is a bit tender, it is a good ‘doer’ and makes an important statement in the garden.” Stuart Lowen, marketing manager, Ball Colegrave, Oxfordshire “Diascia is susceptible to Botrytis, so avoid high humidity and wet foliage. When the plants are young, allow the media to dry slightly between watering. “The D. Whisper series is great for 12cm pots, patio containers and hanging baskets. The D. Wink series offers plants with a compact habit, with a great performance in large containers. They need a well-drained, disease-free, soil-less medium, ideally with a media pH of 5.6-6.0. “The best way to control the growth of Diascia is to grow the crop cool, provide bright light and apply moderate, regular water stress to promote flowering and reduce unwanted vegetative growth. Pinch plants back seven to 10 days after transplanting to improve basal branching. For a larger basket or container a second pinch can be applied.” In practice Peter Jackson, director, Scotsdale Garden Centre, Cambridge “We plant up a low dish of diascias for the period when they are at their best, and this works very well to get the attention of the customer. We also tend to include them on our alpine benches —they appeal to the same sorts of gardeners, and are ideal for pots and containers. “But the thing to watch is the watering. There are a number of plants that, for us, do not sit well under our normal automatic watering regimes, and diascias are one of them. They must not get too wet, so hand watering, when absolutely necessary, is best.” Species and cultivars:-
