It's one big plant. I'd guess its about 10 yrs old or more. The thing ab out theses, is once the get somewhat big, the get bigger exponentially fast. New leads start (all the flowers are new leads) so next year it will have many more.
I stopped by monday to help wrap the structures up for the cold front coming, and spied 3 leads growing on the back of the mount. I asked for a division and was told... MAYBE. Prolly not, but it would be nice... heh heh!!!
