Clarkia concinna subsp. concinna

Family: Onagraceae · Type: annual · Native

Clarkia concinna is a California native annual found in northwestern California, northern Sierra Nevada foothills, and eastern San Francisco Bay Area (Oakland Hills, Mount Diablo) in mixed-evergreen forest, woodland, and coastal scrub at elevations below 1,500 meters. Flowering from April to July, this plant produces pink to magenta flowers with prominent petal lobes separated by deep sinuses, each petal 15 to 30 millimeters long. Growing with slender upright stems reaching 10 to 50 centimeters tall, it forms delicate branching structures. Its leaves are narrow and lance-shaped, arranged alternately along the stem. The flower's distinctive feature is its deeply lobed petals, with sepals remaining fused only near the tip, creating an intricate and elegant bloom.
