Less than a foot
ground cover plants that are native to California.
ground covers are useful in small spots, borders, or to lower the edges
of larger ground covers. Low ground cover plants compete poorly with weeds.
Use the taller ground covers for larger areas or where you want more drought tolerance. The taller ground covers are generally just easier and cheaper.
Do not be afraid to mix and match, most of the natives look good together. Push up the middle of the planting with higher plants to make a mound, without the pains of using tons of dirt. The plants will be happier without the dirt mound, and so will you. Some plants only grow a foot across, some 8 ft. across, one is a whole lot cheaper to use as a ground cover.
