Clarkia amoena, also known as the satin flower, is native to western North America from central California to British Columbia. Clarkia wildflowers (Clarkia spp. ) derive their name from William Clark of the Clark and Lewis Expedition.
Clarkia is a genus of plants in the Onagraceae family. More than 40 species are currently recognized in this genus. It’s a popular annual in cool climates cultivated in borders and flower beds for its satin-finished, cup-shaped blooms.
The flowers usually bloom from late spring to early or mid-summer. The plants grow up to 30-inches tall on upright to lax stalks that are edged with lanceolate leaves (up to 2.5-inches long).
The four-petalled flowers (2 to 3-inches in diameter) are red, pink, or lavender, sometimes with a spot or blotch at each petal’s base.
