Had off and on luck, had a small area that I removed the soil and replaced it with 40% sand 40% pea gravel and 20% of my "special" compost...did that to about a a depth of 6-9 inches (special only that I made the compost : )). They have done relatively well for the past 4-5 years. They are a spectacular plants; when the light hits them they really illuminate! I have tried, off and on for years, but it wasn't until I changed the soil that I was able to have some sucess .
As Yogi Berra said, “It's tough to make predictions, especially about the future.”
