grass on hill
I'm on a hill facing just South of East in zone 6, with some shade in the AM, but sunny from late AM thru about 4PM. The hill covers about 3/4 acre. Elevation is about 2800'.
I would like to plant some ornamental grasses native to this area, that would control erosion. One type I've seen are clumps of grass along sides of roads that appear to have been planted, and grow to about 2' high and are now growing seeds.
