California Buckeye (Aesculus californica): A poisonous California native.
The California buckeye is a deciduous, woody shrub or small tree, typically 12 to 36 feet tall, though exceptional specimens can exceed 40 feet. It displays a broad, rounded crown and distinctive palmately compound leaves with 5 to 7 finely serrated leaflets. Its showy floral display — dense, upright panicles of white to pale rose flowers up to a foot long — blooms from May through June, with some variation based on climate.
