Chilopsis linearis (Cav.) Sweet ssp. arcuata (Fosb.)

Desert Willow
Bignoniaceae (Bignonia Family)



 

Desert willow is a large willow-like shrub or small tree from 4' to 21' tall with few to many slender, drooping branches and long, narrow, terete fruit pods 6"-12" long.  This plant is common below 5000' in sandy washes and watercourses of both deserts, and adjacent areas of the Transverse and Peninsular Ranges, blooming from May to September.  The leaves are simple, alternate (though sometimes opposite or even whorled on same plant) and linear to lance-linear.  The leaves are deciduous and often fall off during the dry season, leaving the shrub seem almost lifeless.  The flowers are large and showy, and range in color from lavender to pink to whitish, with purplish lines and yellow ridges in the throat and on the lower lobes.  They have corollas to 2" long with five irregular lobes, barely two lipped, and four included stamens.  The calyces are two-lipped, densely hairy, and sometimes slightly white-woolly.  This is the only species in its genus and the only genus in this family in California.  Another member of the Bignoniaceae that people may be familiar with is the tree Catalpa. These pictures were taken at the Environmental Nature Center in Upper Newport Bay and at the Living Desert in Palm Springs.
