Aesculus pavia - Red Buckeye
Family - Hippocastanaceae
Size - Clump forming, rounded, large shrub/small tree to 15 to 20 feet tall with a comparable spread. Seems slow until established, then becomes slow to medium in growth rate. A tree on campus has grown about 8 feet in 6 years.
Foliage - Palmately compound, 5 leaflets. Dark green in summer, Fall color is a yellow-brown often dropping early.
Flower/Fruit/Seed - Flowers are grouped in upright panicles, each panicle is about 6" in length with each flower approximately 1 1/2" long, rose-red. Fruit are a tan dehiscent capsule approximately 2" in diameter containing 1 to 3 shiny, dark brown seeds and ripening in the Fall.
Bark - Light brown, smooth, with lighter toned gray markings on older wood. Reminiscent of American Beech bark on young trees.
Pests and Diseases - Some powdery mildew, but nothing serious.
Landscape Use - Small tree for the home landscape. Would do well as a focal tree in the shrub border or as a patio tree.
Performance - 9 Hardy from zone 4 to 8. Prefers a moist, well drained soil, full sun to part shade. The tree on campus which is planted in less than ideal soil conditions has performed well. It receives no supplemental irrigation. Seems to be a fairly adaptable and tolerant tree. Native to the southeastern U.S.
