California Buckeye
Aesculus californica

· also called california buckeye
Honeybees are strongly attracted to California buckeye's early-season nectar and pollen, often foraging heavily during peak bloom in May. Warning: the nectar and pollen are toxic to honeybees, causing wing deformities and colony losses — beekeepers should relocate hives away from stands of this tree. Brief but intense resource in dry years when other sources are scarce.
