Douglas's golden violet (Viola douglasii)
Douglas's golden violet (Viola douglasii) is a California-native plant with a strong affinity to serpentine soil. This perennial herb has bright yellow flowers whose lower petals are adorned with reddish brown streaks, and whose lateral petals have short hairs at the throat. [Photographer's note: Most sources list the common name as "Douglas' golden violet" or "Douglas' violet," but the grammarian in me just can't bear to leave off the final s. Alas, I suppose botanists would argue this is just one more reason to stick to scientific names.]
