Your advice to get a "successful" Acanthus Mollis

rouge21_gw (CDN Z5b/6a)

I have always refrained from buying any "Bear's Breeches" as I think I have the impression that it is a bit 'tricky'...in terms of survival and flowering. But last week I picked up this specimen as an impulse buy.



So what can you tell me as to why your A.M. does well? (Or did poorly?)

    It is my understanding that Canadian hardiness zones are not the same as the USDA hardiness zones, as they are based on different criteria. It was also my understanding that the Canadian zonal system is approximately one zone higher than the US equivalent. So rouge's zone 6a is really USDA zone 5a, which is why I asked my original question about hardiness.

    Or is all this completely changed?
