Aesculus pavia Red Buckeye1

Edward F. Gilman 2


Red buckeye is a small North American native tree. It is capable of reaching 25 to 30 feet tall in the wild, though it most often reaches 15 to 20 feet high when grown in cultivation (Fig. 1). Red buckeye is most popular for its springtime display of three- to six-inch-long, upright, terminal panicles composed of 1.5-inch-wide, red flowers that are quite attractive to hummingbirds. These blooms are followed by flat, round capsules that contain bitter and poisonous seeds. The large, dark green, palmate leaves usually offer no great color change in fall, and often drop as early as late September.

Use and Management

The coarse, open structure and the light brown, flaky bark is quite attractive and offers great winter landscape interest. Branches arise from the typically straight trunk at a wide angle, forming a durable structure. There are many, small-diameter branches with an occasional upright, aggressive one growing as large as the trunk. Main branches begin forming low on the trunk and remain there when grown in the full sun.

The tree is best used as a novelty patio tree or as part of a shrubbery border to add bright red color for several weeks in the spring and coarse texture during the rest of the year. Plant it in a medium- to large-sized residential landscape as a very coarse accent. Extremely coarse in winter without leaves, red buckeye will attract attention with the bright brown or tan bark reflecting the rays of the sun. Lower branches can be removed to allow for clearance beneath the crown, but the tree looks its best planted in the open to allow branches to fully develop to the ground.

Red buckeye will flower well in rather dense shade but takes on its best form when grown in full sun with some afternoon shade on moist, well-drained soil. It is native along moist stream banks and is not very drought-tolerant.

The cultivar 'Atrosanguinea' has deeper red flowers; 'Humilis' is a low or prostrate shrub with small panicles of red flowers. Hybrids between Aesculus pavia x Aesculus sylvatica have been seen, bearing red and yellow flowers.

Red buckeye is easily grown from seed, with plants flowering after three years.
