Limnanthes douglasii ssp. douglasii
Meadowfoam is one of many annual species that grows in seasonally wet depressions called vernal pools. As these pools dry up in spring and early summer, various annual plant species flower in concentric rings of showy color. The dense mass of white and yellow flowers forms a foamy blanket and give the Meadowfoam its common name. With age, the petals fall away and the persistent sepals clasp the seed-bearing nutlets until they disarticulate from the floral receptacle.
DISTRIBUTION: Wet meadows from the North Coast and outer North Coast Ranges to the Central Coast and San Francisco Bay Area; < 700 m.
