Schnickel Fritz took a while to get established but once it did, I've found it to increase quite a bit. I've dug out chunks of it and given away to friends. It's always a double bloom. Yes, it is short and I really need to move mine out away from the taller DL's that I have (some day). One thing I have noticed about SF is that it tends to multiply by sending out a root underground off to the side. I know there is a name for that, but can't think of it right now. This makes it easier for me to dig out chunks to share. Oh, yes, SF is almost always the very first DL to bloom in my zone 5 garden.
