Commonly known as California buckeye, California horse chestnut
The horse chestnut, or buckeye, is a genus of about 15 species of deciduous trees and shrubs from southeastern Europe, the Himalayas, eatern Asia and North America.
Striking for their large flower spikes in candles most are too large for average gardens and are popular street and park trees.

They provide nectar and pollen for insects, particularly bees, and the fruit "conker" is eaten by mammals.
