Hardy Impatiens

I keep on telling people that these things are hardy but they don't really believe me. The look on their face says 'Yes but not really', and I say, no, they've all survived outdoors in the ground both here and on our heavy soil at home, and they still don't really believe it, but I can promise you. There is in fact a narrow shady raised bed at the nursery only 6ins deep over the Mypex where three of them - arguta, uniflora and puberula are in danger of taking over. They even seem to do quite well in dry shade under shrubs. Almost too good to be true.
People are always wanting plants for shady places that flower on and on all summer. Well here they are. Come and get them...

Impatiens arguta, originally uploaded by peganum.

Impatiens arguta

The most reliable hardy species here in Sussex -  even in dry shade. A vigorous species with large tubular purple flowers on red stems. Ideal for any shady situation and flowering all summer. 

A large plant in the border at the nursery in late October. What's not to like?
1L pots ~ £8

Impatiens puberula

Another hardy purple flowered species, this time with soft green, somewhat fuzzy foliage. The flowers are more chubby with dark purple lips and a paler 'bag' behind, if you see what I mean.

Needs the same conditions as arguta but is more spreading as the stems root where they touch the ground.

Impatiens stenantha

Another excellent hardy species for exactly the same conditions as the others. The foliage and stems have a distinct wine purple tint.

Caryopteris divaricata

The name Caryopteris is usually associated with a bunch of rather grey twiggy subshrubs grown mainly because they flower very late in the season (C. x clandonensis and the like). C.divaricata is very different - making a lush green upright bush and dying down completely in winter. The late flowering is the same but the flowers themselves are much more interesting as can be seen from the photo. Those of you who know the tropical Clerodendron (or Rotheca) myricoides (or ugandense) would be right in thinking they look suspiciously similar, with those long curling filaments and rounded purple blue petals. They are related.

Another well-known purveyor of rare plants describes the flowers as merely ‘harmless’ which I think is a bit unfair. They’re not huge or especially plentiful, but they are beautifully crafted and jolly pretty. The only down side is the foliage which has an odd odour (one customer calls it The OXO plant) so don't plant it too near the path unless you like that sort of thing. Also the stems are quite brittle so best planted amongst other things out of the wind.

Totally hardy and very adaptable. I will soon have a few of the pink flowered form available too.

Salix gracilistyla melanostachys

Salix gracilistyla melanostachys, originally uploaded by peganum.

A very wacky willow for you, this time grown for it's bituminous black catkins in early spring which sprout pale yellow anthers and have red highlights.
It's hard to get a good shot of this from a distance with any 'interference' in the background, but the black catkins, (see photo below) are striking. Potentially a large shrub but responds well to quite hard pruning immediately after flowering.

Senna hebecarpa

I'm not sure why the North American Sennas are not better known in the UK. I know two of them reasonably well - hebecarpa and marilandica (both sometimes included in Cassia.) The former seems to be the better of the two. They're big exotic looking plants but completely hardy given their distribution as far north as the Great Lakes.
The foliage is lush and the flowers give a good show in the latter part of the summer.

Ideal for prairie type plantings with other native Americans (so to speak) they grow well in moist rich soils in full sun but should tolerate some shade and drought.

Tinantia pringlei

Tinantia pringlei, originally uploaded by peganum.

A hardy Mexican relative of the popular houseplant Tradescantias. It dies back completely in winter but comes back strongly from the roots in spring forming a dense ground-cover. The foliage is black spotted (not diseased) and there is a succession of the little three-petalled mauve flowers through the summer.
Completely hardy through the last few winters here in Sussex, and in fact inclined to turn up in unexpected places around the garden.
