Aeschynanthus 'Frostfire' - grown by Al and shown here in his greenhouse. It's been donated and in my possession for about another week :)
I've seen it loaded with flowers, so this isn't its best.
I remember when this was a wee li'l cutting 2 or 3 years ago - Al has been kind enough to let me propagate the plant in his greenhouse. Now it's 4-hanging-pots big - and that's after numerous trimmings.
This is described by Lyndon Lyon as a free-flowering Aeschynanthus with strong foliage and good trailing habits.
