Family: Onagraceae · Type: Herb · Native

Clarkia concinna subsp. concinna is a native California herb in the Onagraceae family, recognized by prominent petal lobes separated by deep sinuses and stigma exserted beyond anthers.

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.

How to tell it apart

vs Epilobium: Clarkia seeds lack a hair tuft and its petals are broad, often clawed or lobed; Epilobium and Chamerion have seeds bearing a tuft of silky hairs and long, thin capsules.; vs Oenothera: Clarkia flowers are pink to lavender-purple and its buds nod before opening; Oenothera flowers are generally yellow (or white), larger, and open at dusk.; vs Camissonia: Clarkia petals are pink-purple, often fan-shaped or lobed with a distinct claw; Camissonia and Camissoniopsis have yellow, unlobed petals.; vs Sidalcea: Clarkia has 4 petals, an inferior ovary, and a 4-lobed stigma; Sidalcea (checkerbloom) has 5 petals, a superior ovary, and a central mallow staminal column.; vs Gayophytum: Clarkia is showy with petals 10-35 mm; Gayophytum has minute white-to-pink flowers only a few mm across on thread-like branches.
