Here in very wet coastal Northern California I find the cultivars I've tried are not only, not thugs, but disappear in the ground, but then I haven't tried some of the ones people are talking about. The one I have in my garden that is either just the species or maybe Wisley on the other hand is very tough requiring no special treatment, long blooming and spreads a lot. I have a white one shared by someone that does well in pots, but did not return in the ground. And this year I accidentally left a pot grown from seed of the Alberto Castillo cultivar (which I understand wouldn't make it the cultivar unless it came true from seed) where it stayed damp during dormancy. Most of my Ipheions dry out completely even though we had a discussion on this list about this and the man Alberto Castillo suggested that plants would not be happy with this treatment and would do better with some summer water. So I had a chance to test this theory. Instead of helping, none of these bulbs came up when my others did. The others came into growth in October and the pot that had remained damp appeared in January and has yet to bloom. So in this case too much moisture was worse than none at all. 'Rolf Fiedler' is a lovely color of blue, but a short bloomer for me. It's always interesting the different experiences we have with the same plants.
