Red buckeye is a deciduous understory shrub or small tree with an open, rounded crown. Its maroon to red, tubular flowers are borne in showy, terminal clusters on red pedicels. Leaves are palmately compound with long leaf stalks. They are oppositely arranged. Leaflets are elliptic to obovate with finely serrated margins. The fruit, which appears in the fall, is a large, brown capsule that splits to reveal one to several seeds that look like chestnuts.*
Red buckeye typically flowers in late winter through spring. It is one of the first of the red tubular flowering plants to bloom each year, and is important food source for returning hummingbirds and butterflies. It occurs naturally in moist and calcareous hammocks, slope forests, and upland hardwood forests.
