I need a promptly growing ground cover that will cover about 300 sq ft. It is mostly within the shade.
Answers:    I like ivy. Its nice gloom green color stands out and it does very resourcefully in the shade. Creeping myrtle is also nice and it will enjoy a little purple flower on next to grren leaves. Pacasandra is also very nice. Japanese lantern grow VERY fast and within the fall produce an ginger lantern type flower on it also very nice.
I love phlox. I hold some in the sun and shade.
