Andrews' Clintonia

Clintonia andrewsiana is a perennial herbaceous plant that spreads by means of underground rhizomes. It is the largest plant species in the genus, standing 30 to 80 cm (12 to 31 in) tall. Around the base of the plant are 5 or 6 oval-shaped, dark green leaves, each 20 to 35 cm (8 to 14 in) long and 5 to 15 cm (2 to 6 in) wide. The tall, erect inflorescence consists of a terminal umbel with 10–20 flowers and up to three lateral umbels with 2–4 flowers each. Each flower has six pink to reddish-purple tepals 1 to 2 cm (0.4 to 0.8 in) long and six stamens about half as long as the tepals. The fruit is a blue or blue-black berry approximately 1 cm (0.4 in) in diameter.

Clintonia andrewsiana is found along the West Coast of the United States, from Monterey County in central California north to Curry County in southwestern Oregon. It prefers the shady, moist areas of the coastal redwood forests. The range of C. andrewsiana overlaps with that of C. uniflora in Humboldt County and Del Norte County in northwestern California and Curry County in Oregon, but the two species are readily distinguished by their flowers. C. andrewsiana has multiple flowers arranged in one or more umbels while C. uniflora has a single flower with white tepals. The tepals of C. andrewsiana are a deep claret red.
