Horse Chestnut (Aesculus hippocastanum) is a large deciduous shade tree native to the Balkan Peninsula and widely planted throughout North America for its impressive spring floral display and dense canopy. In late spring, the tree produces upright panicles of white flowers, often marked with pink or yellow highlights, that can reach 8 to 12 inches tall. The flowers attract bees and other pollinators before giving way to distinctive spiny seed capsules containing glossy brown seeds commonly called horse chestnuts or conkers. Mature trees typically reach 50 to 75 feet tall with an equally broad, rounded crown that provides excellent shade. Horse Chestnut grows best in full sun to partial shade and moist, well-drained soils. While valued as a specimen and shade tree in parks, campuses, and large landscapes, it requires ample space to accommodate its mature size. The seeds, leaves, and bark are toxic if ingested and should not be confused with edible chestnuts.
