Ceanothus foliosus, commonly known as Wavyleaf Ceanothus, is an evergreen subshrub or shrub native to the chaparral and mixed evergreen forests of California. It typically grows under two meters in height and can be tall and erect or low-lying and sprawling in form. The shrub features small, evergreen leaves that are one to two centimeters in length, toothed along the edges with glandular knobs. During the spring and winter, it produces petite inflorescences on naked stalks, bunched with blue or lavender flowers that have prominent yellow anthers, adding a splash of color to the landscape.

Wavyleaf Ceanothus is valued for its drought tolerance and ability to thrive in poor soils, making it an excellent choice for water-wise gardens and native plant landscapes. It is often used for slope stabilization and habitat restoration due to its extensive root system. In residential gardens, it serves as an attractive ground cover or low hedge. For best growth, it requires full sun to part shade and well-drained soils. While it is generally low-maintenance, it can be susceptible to root rot if overwatered.CC BY-SA 4.0
