Vine Hill clarkia is a late-blooming, slender annual herb with large white or pinkish flowers. This species grows in habitats with sandy loam soils. Historically, it is known from only two natural occurrences in the Vine Hill area of Sonoma County, California. One of these is extirpated, leaving a single native population. A transplanted population exists at the California Native Plant Society's one-acre Vine Hill Preserve (CDFG 2002).
Distribution & Occurrence
Chaparral, valley and foothill grasslands in acidic sandy loam soils (Skinner 1997).
|Vine Hill Clarkia is currently known from two populations in southern Sonoma County, California, one natural and one planted in a reserve. The natural population contains 2,000 to 5,000 plants; the planted population has fluctuated between 200 and 300 plants.|
