I dug my two Harvey Koop plants and they had very few tubers. One had 3 and the other only 2. Now we will see if they store during the winter. I had only one or two nice blooms off them but I see why people like it so well.

It seems to me . . . most of my favorite plants? The tubers are few. There are a few exceptions . . . My Hillcrest Kismet, I stored the mother tuber and two tiny ones, that I doubt will make the winter (which is why I kept Mom.)
