Botanical description:

California buckeye is a large shrub or tree up to 23 feet (7 m) tall. The 2-to 6-inch-long (5-15 cm) leaves are deciduous and palmately compound. Flowers are borne on a terminal panicle 4 to 8 inches (10-20 cm) long. The pear-shaped, light brown fruit contains one to six glossy brown seeds 0.8 to 1.2 inches (2-3 cm) in diameter.

The bark, leaves, and fruits contain the neurotoxic glycoside aesculin, which causes hemolysis of red blood cells.

Seasonal development:

California buckeye flowers from April to September. The nectar of the flowers is toxic to the Asian/European honeybee, so the trees should not be planted near apiaries.

New leaves emerge from March to June while soil moisture is abundant. Fruits ripen from September to October and are dropped from November to December.
