It is unusual for a ceanothus to be found growing at subalpine levels, but Mahala Mat is very comfortable there provided it receives an insulating layer of snow in winter.

High winds and high temperatures are not favorable for this low growing evergreen groundcover; it needs a partial sun situation with good drainage.

When content Mahala Mat will form a dense matte of glossy serrated leaves and produce pale blue flower clusters and bright red horned fruit.

Ceanothus prostratus is native to the dry mountainous regions of Washington, Oregon and California and can be occasionally found in Idaho and Nevada, USDA zones 5-8.

This is a very attractive plant given the proper growing conditions. It has gained favor as a ground cover in many commercial situations.
