Bought this on impulse despite knowing this family is a thuggish one.
Im fairly sure ??ou will agree this too is invasive but I was it is well behaved.
So, folks, do you grow it? Have you grown it?
One of my customers grows it Verdun and it seems fairly well behaved. Its in a sunny border, sandy soil and seems happy enough
As my Joe Pye does so well thought I'd get a chocolate last year. Gave it huge pile of mulch but lost it last winter, as it was not too cold I decided to give up on that idea up here.
Did not survive here either, though the ordinary one does well.
I've got 4 of these around my garden & have never found them thuggish, although that might be something to do with the "pan" 18 inches down (thanks, builders!).Must admit it's one of my favourite plants.
I have grown it for several years and have found it very well behaved in a number of different situations. It is easily reproduced from cuttings, although I am sure division would work as well.
