When I finally get around to digging up a weedy overgrown clump that hasn't bloomed in ages, I love to find a hidden tag wrapped around a root that is just barely readable, and tells me that the DL I am digging and dividing is one of my long lost favorites! The only way to deal with a clump like this that has quack grass spearing its roots is to divide it fan by fan, and when you do this you soon have an abundance of this cultivar. I did this with a very old clump of Franz Hals a few years ago, and it has just increased amazingly, and grown taller and much more branched and budded than it ever did before.
I will have to look for the pic.
