I need to get a hardy groundcover for a steep slope in my back yard. This area gets mainly shade in the summer, due to large trees, and sun in the winter. The soil in our area is horrible. It's not even red clay. It's more like red rock, and the water tends to run off due to the slope.
Grass doesn't grow well in this area, but some weeds pop up. Some spots are very barren. Any ideas?
