Looking for drought resistant groundcover, steep slope
I have spent years seeking a drought resistant groundcover (preferrably blooming) that will survive our very hot summers in NC,on a very steep slope that is impossible to mow. I need something that requires little to no care (slope is not near house or water source). The real problems are no water is available (at least easily available), poor soil, deer, full sun, and like I said, very steep slope. The area I need to cover is about 100 ft. I have tried various grasses, I was told to try vinca (too hot for it), verbena became very scraggly, daylillies are not really spreading well, etc. I do have (please bear with my spelling) Muhlu grass (the pink puffs at the end of the stalks). However, it is just maintaining its green color and no pink occurred over the past two years. I thought about crown vetch, but, nurseries are trying to talk me out of it. I truly need some very sound advice. I would greatly appreciate it. The weeds are very unappealing!
