Your expertise is greatly appreciated
Long time enjoy reader, but 1st time poster and looking forward to your expert feedback.
I am in zone 9, Inland Empire, Southern California. I have a big back yard slope split by a v-ditch in the middle into 2 parcels. Please see picture. The slope is a little less steep(23 degree) than 2:1. Both parcels are about the same size, about 100'(horizontal) x 60'(slope) each.
I am thinking there should be some erosion control vegetation above the v-ditch. Some drought tolerance, desertscape or mix with some gravel or rockscape will save some water. The follow are some prefer plants. Let your imagination to be materialized on my back yard. Thank you in advance.
Not limited to the following:
Crepe Myrtle variety colors
Senecio ground cover
Lantana variety colors
Bronze & Green Flax
Area for some fruit trees
