I need a ground cover for an hillside. Its about 25ft sloped up and about 60ft long. Its about a 40 degree slope, full sun but not extremly dry. Looking for something other then Pachysandra which is everywhere here. Customer would love something that with some color or flowers. This is in the back corner of a yard, customer does not want to get to complicated with landscaping it now but finds it difficult to mow nicely. Just wants something better when looking beyond their nice lawn and gardens. Located in Southern New England as to hardiness.
