Time will tell.

I can't remember if it was this one or one, with green, frilly, flowers, living at the other end of the border. However this afternoon on one of my "prowls" I spotted a number of small, green, bouquets on this particular plant. A short time ago I picked one and "soiled it". It is still there, so I'll stick this one in as well and see if my suspicions/hopes are justified and we get an attack of asexual/vegetative reproduction.
