Wow, Don, that's a terrific number of blooms! I've  heard anemone species can be promiscuous...perhaps it is a cross, or two or three. Did you get a piece of this one?

On my travels for work, I came across this patch of which, upon closer inspection, appears to be Anemone hupehensis. Japanese Anemone (?)  
I have never seen one bloom with such profusion!  Is my ID incorrect, or is there a certain cultivar which is particularly floriferous?  I have had an unnamed cultivar for years (east facing, behind my garage), but it has never put on a show like this one (which has a north facing open exposure).
