Aesculus pavia var. pavia (Scarlet buckeye)
Marcus, Joseph A.

Aesculus pavia var. pavia L.

Scarlet buckeye, Red buckeye, Southern buckeye, Firecracker plant

Hippocastanaceae (Horse-Chestnut Family)

USDA Symbol: aepap

USDA Native Status: Native to U.S.

Native from North Carolina south to northern Florida, north to southern Illinois, and west to the eastern edge of the Edwards Plateau in central Texas, Aesculus pavia var. pavia is an attractive spring-flowering shrub or small tree, blooming in some years as early as February, with showy red flowers. Frequent on limestone ledges above streams and also found on a variety of well-drained, usually acidic woodland soils in the Southeast. On the central Edwards Plateau of central Texas, may show hybridization with the yellow-flowered var. flavescens (Sarg.) Correll, the common form in the western part of the Edwards Plateau. Large leaves with leaflets radiating from the tip of a long petiole. Bark on young branches smooth, gray to brown, roughened on older ones. Leaf blade palmately divided into 5 leaflets; petiole up to 6 inches long and leaflets of equal length, tapering more gradually to the base than to the elongate tip, and with serrate margins. Flowers tubular, 1 to 1.5 inches long, on an upright axis as much as 8 inches tall. Fruit a rounded capsule 2 inches in diameter, brown, with a slightly roughened surface, persisting after the leaves have fallen; seeds 1 to 3, shiny.

This is the red-flowered variety of species Aesculus pavia, found throughout the species range except the westernmost edge of the Edwards Plateau in central Texas, where variety flavescens takes its place. It ranges in height from 10 to 40 feet, with heights diminishing the farther west you go from the Mississippi Valley. Long popular for its brilliant, hummingbird-attracting spring flowers and rich green foliage, it is found in nature most often as a plant of woodland edges, where it can get morning sun and afternoon shade. In a planned landscape, it should be placed where it wont be prominent after July, as it loses its leaves by the end of summer.
