This erect shrub can be found across the Santa Monica Mountains (north of Malibu, CA) among chaparral and oak woodlands. Baccharis malibuensis can be identified by its linear, serrated leaves and cream-colored flowers that are only in bloom for one month out of the year (August). B. malibuensis is classified as a Critically Imperiled species due to ongoing urbanization and local off-roading. With its stems growing clusters of 20-30 flowers apiece, this shrub gets frequent visits during blooming season from pollinators including the Common Buckeye (Junonia coenia).
