I have one Delosperma cooperi, a noid fucshia-colored one. I had no idea all these different colors were available.
I have been trying to create the same effect with Livingstone Daisy; unfortunately so far the Livingstone Daisy aren't very cooperative. At least this year I have gotten them to blooming size. Seeing this photo has re-energized me to figure it out.
Good job!
