Clarkia – Winecup

Winecup Clarkia (Clarkia purpurea) is a native annual forb (herbaceous flowering plant) in the evening primrose family, known for its vibrant, cup-shaped flowers. This species is native to western North America, primarily found in California but also extending into Oregon, Nevada, and Baja California. It typically grows in open woodlands, grasslands, and meadows, thriving from sea level up to around 6,000 feet (1,800 meters) in elevation.

The plant blooms from mid- to late spring into early summer, depending on the climate and elevation. The flowers are usually pink to purple or maroon, with four petals forming a shallow bowl or “winecup” shape—hence the common name. Some varieties may feature speckling or a darker central blotch on each petal. The stems are often reddish, and the narrow, lance-shaped leaves are medium green.

Winecup Clarkia is a valuable addition to native plant gardens, pollinator habitats, and restoration projects, attracting bees and other beneficial insects. It prefers well-drained soils and full sun to partial shade and is drought-tolerant once established.
