Low, bushy native of arid southern California and a few nearby states (AZ, UT, BC) whose seed contains a much-touted liquid wax or oil. Cultivated for that oil, which is used in cosmetics and shampoos. The oil withstands high temperatures and thus has industrial uses as well.

Leaves are light green, yellowish green, or gray-green, oval and opposite. Plants are extremely drought tolerant when established. They are male or female (dioecious) and the male flowers are much more abundant, producing prodigious quantities of pollen. Flowers appear in winter and spring. The fruit bears a single large seed which is easily harvested when ripe.

This is often a dominant shrub in the coastal chaparral of northwestern Baja California, dwarfed somewhat by rocky soil and infrequent precipitation, to about 2-3 feet high and wide. In gardens it can grow larger.

An excellent low-care plant in mild Mediterranean climates which requires zero irrigation and is not picky about poor soil. Best form in full sun. Easy to start from seed (in winter if in the native area) and relatively quick to reach landscape size (1-2 years). Seeds are edible raw or cooked, if not particularly great tasting. Leaves may be used by animals for forage.
