Very lovely. I was just looking at Elise Lewisia. Blooms in 4 - 5 months from seed, no cold stratification needed and can bloom 4 times a year and is hardy in my zone. Not as pretty as some of them, but good enuff for me with those qualities.
My wife and I talked about this and we had this in a rock garden 25 + years ago. Her mind works better than mine.
