I just posted a picture of Cosmic Kaleidoscope in June Blooms.
Cosmic Kaleidoscope died the first winter I had it, but It made a proliferation and two years later I have a full grown plant that is blooming. I think it has a prolif on it this year. I have proliferations all over my seedlings. Not many on registered daylilies.
I put mine in a container that holds water and make a quick sand mix. (very wet sand) Everytime I can remember, I add water to keep the sand wet. I used a small plastic trash can last year. Just before winter, they are potted up and left outside to survive until spring when they go in the garden. Most of them survive.
