- Comments:Flowers are attractive to Ruby-Throated Hummingbirds and bloom in St. Louis at about the same time that the hummingbirds return to the area in Spring migration. They are very showy when in flower. The coarse, open structure and the light brown, flaky bark is quite attractive and offers great Winter landscape interest. Red Buckeye will flower well in rather dense shade but takes on its best form when grown in full sun with some afternoon shade in moist, well-drained soil. It is native along moist stream banks and is not very drought-tolerant.
In spring, showy red, 9-in. panicles bloom, attracting hummingbirds. One of the few small trees that will flower in dense shade. Grows 10-to 20-ft. tall with round to pyramidal shape. Works well as tree or shrub. Resists disease and pests. Plant in full sun to shade. Zones 4-9.
