Another beauty from South America (the woods of Argentina and Bolivia), there are a few plants of “mini angel’s trumpet” in the Alpine Garden. Conventional wisdom was that this plant would only be hardy to -5°C, but it survived the winter two years ago which dipped to -13°C. Admittedly, much of the above-ground part of the plant died, but it seems to have recuperated.
Iochroma is a member of the plant family Solanaceae, one of my favourites. I can’t help but admire a group of plants that includes potatoes, tomatoes, tobacco, hot peppers and deadly nightshade (Atropa belladonna).
