Horse Chestnut

Honeybees visit horse chestnut trees primarily for abundant pollen and nectar during late spring bloom, providing an important early-season resource before many native plants flower. Peak bloom occurs in May to June, with large panicles attracting foragers. Although some older reports mention potential toxicity from saponins in nectar and pollen, modern observations show bees collect from it without widespread issues, but it's not a major honey flow contributor.
