A deciduous native tree with pink to white flowers in spring, followed by early summer dormancy in dry climates. Excellent for drought-tolerant landscapes and adapted to California's Mediterranean climate.
Why grow it
California buckeye offers advantages in Mediterranean climates where summer dormancy is an asset rather than a liability. Unlike many deciduous trees that leaf out continuously through the growing season, this species naturally sheds leaves during hot, dry months, reducing water demand and maintenance in established landscapes. Its early spring flowers attract pollinators, and the silvery bark provides winter interest after leaf drop.
Watch out for
This tree responds to heat, wind, or drought stress by dropping leaves prematurely, which is normal physiology but may appear as poor establishment to gardeners unfamiliar with the species. Bagworms, Japanese beetles, and borers can cause damage, and powdery mildew, rust, and anthracnose occur under favorable disease conditions. The plant prefers full sun to partial shade and should be sited accordingly to match its natural canyon and foothill habitat.
