looking for a short, drought tolerant groundcover
I've moved into a home with a relatively steep backyard. The previous owners just let it be wild back here, and now that it has started to get warmer, it has gotten pretty hairy back there quickly.
Since I have a dog back there part of the time, and my area is known to have some issues with rattlesnakes, I was hoping to eliminate (or reduce) the weeds with a groundcover that is short enough to be unattractive as a habitat to snakes. maybe 4" tall at the maximum.
The area is about 80' x 80', with part full sun, part very shady.
The criteria I am looking for are:
1. Drought tolerant
2. Short to the ground
3. Not poisonous to dogs
If anyone has suggestions, I'm all ears. I was thinking maybe some Muehlenbeckia axillaris, but I can't find any at the local nurseries, and I'm not sure whether or not it would damage my trees.
In addition, since I'm in the north, hilly part of San Antonio, the soil here is pretty thin, with rock underneath.
