Solanum umbelliferum incanum

Solanum umbelliferum incanum
A very pretty Californian species combining good sized lavender flowers all summer, and greyish stems and foliage on a low spreading subshrub. Not at all coarse or weedy.
Solanum umbelliferum incanum
This is untried in the UK to my knowledge but is rated as z7 in the USA. Full sun and excellent drainage will probably be the crucial things. If not then it'll be a nice container plant

Impatiens ugandense

Impatiens ugandense
A gorgeous tall species from (you guessed it) tropical East Africa with large white flowers, delicately marked with pink, and good quality fresh green foliage.
Impatiens ugandense
Not hardy but an easy and undemanding species that requires only frost-free conditions in winter and can be stood outside in summer.

Psoralea glandulosa

Psoralea glandulosa
A very lovely light and airy shrub with pea green leaves and blackish stems and slim racemes of violet and white pea flowers in summer. Very fresh and remarkably hardy here.
Psoralea glandulosa
A nice change from the more solid presences of so many other ‘hardy exotics’.

Buddleja colvilei large leaf form

Buddleja colvilei large leaf form
B.colvilei is known for its relatively large rich pink bell-shaped flowers - much larger than any other species that I know of. This is a very rare form with large greyish felted leaves up to 20cm long, and is descended from a plant that used to grow against the house at Borde Hill.
Buddleja colvilei
The flowers appear in mid spring on the previous year's growth and can get frosted off in bud, so a very sheltered situation is required in all but the warmest areas.

Teucrium fruticans Azureum

Teucrium fruticans azureum
A strikingly better form of the species than the commonly available one. The flowers are a good strong clear blue and the stems, new shoots and leaf reverses are pure white. An easy but wide-spreading species - not for a small space. Flowering over a very long period from early spring into summer, it can be cut hard and will flower on the new shoots.
Teucrium fruticans Azureum
It is possibly a bit less hardy than the common form but I've found it easy and vigorous in a sunny dry spot, especially against a sunny wall

Abelia (Linnaea) floribunda

Abelia floribunda
A very striking Mexican species with long tubular dusky pink flowers and small rounded evergreen leaves. The lax spreading habit means it might be best treated as a wall shrub, but I rather like it growing through other shrubs.
Abelia floribunda
It does need shelter and warmth to flower well but is otherwise easy.
The sinking of Abelia (and also Dipelta and Kolkwitzia) into Linnaea has upset a few people but it does actually make sense if you understand the science.

Vicia gigantea

Vicia gigantea
This is a good pink form of a Californian native vetch. In the wild a potentially vigorous coloniser but here I've found it no more so than some of the popular climbing Lathyrus such as L.latifolius, and it makes a very nice change from that with its fresh green pinnate foliage and spikes of rich pink flowers.
Vicia gigantea
Even so I'd give it plenty of space somewhere it won't swamp small treasures. Spring flowering - cut it back to the ground after flowering for fresh new growth.
