Ground cover to replace grass
I'm tired of mowing, and need some kind of living ground cover to replace part of the lawn on a slope. The area is about 100' x 30'. Gravel is unacceptable, and mulch is too expensive. Is there some kind of plant that likes full to partial sun that would fill in the large spaces between evergreen trees and sporadic wildflower clusters. Preferably, the plant would grow no more than 6" or so tall, and would stand up to occassional drought and foot traffic.
