Name: Evan Pioneer Valley south, MA, USA (Zone 6a)
My A. mollis reached 3'x4' in it's 2nd year. This year it reached about the same size. One peculiarity is the plant seems to take a breather in late June and July followed by a huge burst of new growth starting in mid August. No flowers yet and from what I've discovered it's likely not going to regardless of size. I mulch heavily in winter but according to the MO Botanical Garden site late Spring frost can "...impair or eliminate..." flowering for the season. http://www.missouribotanicalga...
