@Groundskeeper: Well, I guess the first problem was there were no root balls. I bought them online, so they were domant (looked like brown twigs). I had a hard time at first fiquring out which end was what. I prepped the ground as much as I could before planting, but I already placed them in between ground roots and I'm not about to dig them all up again. Most of them are just beginning to show signs of life. Hopefully by next year they'll look better.
I also planted Beacon Silver Lamium along with them (actual plants, not dormant ones). They're doing nicely. Do you have suggestions for other groundcover to go with them?
Thanks for your help.
