I have a East facing slope where no lawn mowers can be used. I like to
have that area coverd with non-invasive plant or grass which bossom
all the 3 seasons. Its about 40'x10' area. Currently its full of
plants that I never know of their names. Some of them I trim with the
edge trimmer. Since the top portion of the slope has about another
60'x10' lawn grass (so no non-invasive plant), I like to have very
good verity or quality of plant grown in the slope. Plant/grass should
be tolerant to drought and disease.

TIA
