No, I just keep buying rhizomes for the ones I really like, just to keep them going each year. I do have a few clumps -- BREAKERS has been happy here -- but mostly they just start fading away, and then if I really like it I'll purchase another rhizome here or there to keep it going, until I finally decide it's time. But if I'm ho-hum about one, you can bet its days are numbered and the neighbors start strolling over to let me know which ones they would like...
