Summary

Oenothera californica, commonly known as California Evening Primrose, is a deciduous perennial herb native to dry open areas, such as chaparral, coastal sage scrub, and desert edges in California, the Southwest US, and Baja California. This plant typically grows to a height of 0.5-1 feet and can spread to about 0.2 feet wide. The California Evening Primrose has a sprawling form with lance-shaped leaves and bears showy white flowers that turn pink with age, usually blooming from late spring to summer.

The plant is valued for its drought tolerance and the delicate, fragrant flowers that open in the evening and close by the next midday, making it a unique addition to xeriscapes and rock gardens. It is also used in restoration projects due to its ability to stabilize soils. California Evening Primrose requires minimal maintenance once established and attracts pollinators such as bees and moths. It thrives in full sun to part shade and prefers well-drained soils. While generally disease-free, it can be susceptible to root rot if overwatered.CC BY-SA 4.0
