Diamond clarkia

Family: Onagraceae · Type: annual · Native

Diamond clarkia is a California native annual found in California Floristic Province (excluding San Joaquin Valley) and Modoc Plateau in yellow-pine forest and woodland at elevations below 2,500 meters. Flowering from March to September, this plant produces pink-lavender flowers with distinctive diamond-shaped petals 6 to 12 millimeters long, often spotted with interesting color variations. Growing with erect stems less than 1 meter tall and covered in fine puberulent hairs, it displays a delicate, slender form. Its leaves range from lanceolate to elliptic, measuring 1 to 6 centimeters long with petioles 5 to 25 millimeters in length. The plant's unique flower structure features eight stamens with blue-gray pollen and petals with broad, two-lobed claws that create an elegant, geometrically interesting bloom.
