Chorizanthe fimbriata var. laciniata
Chorizanthe fimbriata
Variety laciniata is found from San Diego and western Imperial counties southward into Baja California. It can be weedy, especially in chaparral.

Chorizanthe fimbriata is our only representative of subsect. Flava, a taxon of six species otherwise confined to Baja California. These are the most elegant of the annual species in their remarkable flowers. The flower color, the fine divisions of the tips of the tepals, plus the handsome habit make them of potential horticultural interest for the “need-to-be-challenged” gardeners. In addition to C. fimbriata var. laciniata, C. pulchella Brandegee would be a worthy introduction. Chorizanthe flava Brandegee has bright yellow flowers that contrast dramatically with its reddish mature inflorescence branches. The large (7–9 mm) flowers of C. mutabilis Brandegee are a wonder to behold, the yellow floral tube contrasting with the white to red of the tepals themselves.
