Brodiaea filifolia
Also called Thread Leaved Brodiaea, Threadleaf Brodiae
Threadleaf brodiaea is a rare Californian wildflower that grows from a corm and sends up a stalk of bright purple flowers in spring to early summer. It is a federally threatened, state-endangered native of vernal pools and grassland, so it is best grown only from responsibly sourced stock, in a dry-summer, winter-wet setting.
Brodiaea filifolia, known by the common name thread-leaved brodiaea, is a rare species of flowering plant in the cluster-lily genus. It is endemic to southern California, mostly in the region around the junction of Orange, Riverside, and San Diego Counties.
The bulb is a resident of scattered remaining vernal pool and grassland habitats. It is a federally listed threatened species and it has been listed as an endangered species since 1982 on the state level.
This plant occurs in grassland areas, often in floodplains, and it is a member of the local vernal pool flora. It thrives in an acidic – though almost neutral – pH range specifically between 6.1-6.4. These habitats and conditions are becoming increasingly rare as they are being cleared for development, especially as residential areas expand. Undeveloped land near residential areas is degraded by exotic vegetation, mowing and other fire suppression efforts, sewage dumping, grazing of livestock, off-road vehicle use, and other processes such as the displacement and redirection of water sources.
