Clarkia biloba subsp. biloba

Family: Onagraceae · Type: annual · Native

Two-lobe clarkia is a California native annual found in northern and central Sierra Nevada Foothills and eastern San Francisco Bay Area in foothill woodland habitats at elevations below 1,000 meters. Flowering from May to August, this plant produces delicate purple-pink flowers with petals slightly longer than their width, featuring distinctive petal lobes. Growing with slender stems to approximately 30 to 50 centimeters tall, it has an upright, branching form. Its leaves are narrowly lanceolate, tapering to a point and arranged alternately along the stem. When mature, the plant develops small seed capsules typical of the clarkia genus.
