Dietes bicolor

Dietes bicolor
A South African Iris relative with extremely striking round creamy flowers with three bold orange and black blobs towards the centre. The plant gradually forms a dense evergreen tussock, very like a Libertia, with the flowers held on wiry sems above.
Dietes bicolor
Although this plant is happy in a wide variety of conditions it will need a very sheltered well-drained site in the UK or a large pot, brought inside for the winter. The parent plant has overwintered fine in a terracotta pot in an unheated tunnel for many years now, but I haven't planted any outside yet.

Scrophularia calliantha

Scrophularia calliantha
A very choice member of this often rather weedy genus from Gran Canaria. It has relatively large (2cm) pouch shaped flowers – lemon yellow within contrasting with relatively large rich red petals. The resemblance to the related Phygelius is quite noticeable in this species. The foliage is lush rich dark green.
Scrophularia calliantha
Untried in the UK but almost certainly tender, requiring a frost-free greenhouse in winter but flowering throughout so worth it. Any well-drained soil in sun or part shade.

Canarina canariensis

Canarina canariensis
A tender herbaceous climber from the Canary Islands similar to a Codonopsis but with big red and orange striped bell flowers.
Canarina canariensis
Winter growing but not frost tolerant so needing a cool greenhouse

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.
