Birder, I just came back from a brief tour of Plant Delights Nursery in Raleigh. He has a bunch of similar \'drainage\' swales (?not sure it\'s the right term) which he has converted in to an interesting dual type of planting. He has built up the sides to create berms with interspersed big rocks where he has drainage loving rock garden plants, then he has bog loving plants at the bottom (pitcher plants, sweet flag, etc). I thought it might be an idea for you.
Here\'s a picture of my Pulsatilla vulgaris growing in routine (obviously untended) soil in my jungle of a yard. Seems to be doing fine with no coddling.
Mipii, I gave up on Delosperma many years ago, but re-ordered one to try again this year. I blamed my prior lack of success on our clay soil, but planned to try it in a situation with better drainage. We\'ll see.
