California Buckwheat


Native to the western United States.


A perennial broadleaf shrub. Widespread in the San Joaquin Valley, southern California, and along the California coast, it is an excellent source of pollen for honeybees and is planted for this and other desirable features. It also has the ability to become a problem along roadsides and fencerows. Seeds germinate and regrowth begins in mid-spring and plants mature from late summer into the fall.


Mature shrubs may be well over 6 feet high and spread to a diameter of 10 feet. Branches are slightly hairy, and many spreading branches are present. Leaves are tiny and are lance shaped and clustered in groups of 3 or 4 leaves at the nodes. They are less than ¾ inch long and are tightly rolled under. They may have a thin layer of hairs on the upper surface. Flowers are small, white, and borne in very compact clusters at the end of a naked stalk that is from 2 to 6 inches long. As flowers mature they turn brown and remain on the stalk into late summer.

Characteristicts Important to Control:

A native perennial.
