Ground cover for steep wet sloped areas
I have a 125' long, 20' ft high, steep hill in my backyard in the Canonsburg area in Washington County. As with all Pgh weather, it gets direct sun only 15% of the year. It has springs running thru it making the soil extremely wet. The soil is acidic, silty clay and I am searching for weed choking, low growing, hearty, quickly spreading GC that will flower nicely, stay low to the ground, say 4-8" and look like a nice, thick blanket all year round. Presently it is all mulched with various evergreen trees, bushes etc. I am looking to surround the vegetation with GC so I can stop weeding, mulching (it's so steep and wet, I often lose my footing while working on it!) Anyone out there have any success in a simlar setting? suggestions?
