This native starts to bloom at a surprisingly young age. In spring, the red to pinkish-red panicles — almost 1 foot long —draw hummingbirds and, says horticulturist William Cullina, rival the floral display of rhododendrons. A large shrub or small tree, it grows at a moderate rate into a 10- to 20-foot open mound. Large, glossy leaves stay attractive all season, and it does not sucker like some buckeyes. Plant in moist, well-drained soil amended with organic material. Native to the East Coast, red buckeye is an adaptable plant that prefers acidic soil and blooms in sun to full shade, but does better with more sun. Plants can vary in bloom color, including yellow. Cultivars are available.
