That's why I planted mine in alphabetical order. Maybe if people see any differences between the young shoots of different varieties they could post them to help out. Or if you could comment on any differences you can see in yours maybe someone can help. I gave Zoebisch a couple rhizomes I dug up. I had my niece helping and I labelled the rhizomes, but later, it was nagging me that I put the wrong name on one. Well, my shoots came up and Liberty has a fairly vibrant purple color on the stem, while the suspect Sterling did not. The rhizome I gave him has sprouted and the report is purple, so Liberty it is.
