I'd like to suggest variegated vinca. (Common name)
There are some photos is this thread
The thread "Ivy" in
Ask a Question forum
Both the slope on the street level behind the rose, and the rocky slope at the top of my property face somewhat south-east ... more east than south.
Of course the plants look better when I give them some water, but I do not water them more than once a month in a climate where day temps stay in the high 90s to low 100s during the summer months. We do get anywhere from 25 to 50 inches of rain during the winter months. Some snow at my elevation, which rarely sticks for more than a day or two. This year, we had snow that stuck around for a month, but it did not kill the vinca.
It can be invasive, put others site users posting in the thread above seem to be able to control it better than I have.
Smiles,
Lyn
PS... St. John's Wort is moving over from my neighbor's yard and seems more successful at establishing itself on the rocky slope.
