Hemizonia is a genus of plants in the daisy family (Asteraceae). They are known generally as tarweeds, although some tarweeds belong to other genera, such as Madia and Deinandra. Furthermore, Hemizonia is currently being revised; some species may be segregated into new genera.

Range[edit]

The Hemizonia tarweeds are native to southwestern North America, especially California.

Description[edit]

Hemizonia are usually sticky, aromatic, yellow-flowered annual plants which are hardy and competitive, especially in the dry Mediterranean climate of California.
