Noteworthy Characteristics
Halesia diptera, commonly known as two-winged silverbell, is a small deciduous tree or large shrub that is native to floodplains, stream banks, wet woods and swampy areas primarily along the Gulf Coast from South Carolina and northern Florida west to Texas. It grows with a rounded form to 20-30’ tall. Showy clusters (3 to 6 flowers per cluster) of bell-shaped white flowers (less than 1" wide) with deeply lobed petals appear in spring (April-May). Flowers are followed by flattened two-winged fruits (dry drupes to 2” long) that ripen in fall. Oval to obovate, irregularly toothed, dark green leaves (4-8” long). Leaves turn yellow in fall. Bark exfoliates in thin scales.
Genus name honors the Reverend Stephen Hales (1677-1761), English physiologist, chemist, and inventor.
Specific epithet from the Greek words di meaning two and ptera meaning wings are in reference to the two-winged fruit of this plant.
Magniflora Group primarily differs from the species by producing larger flowers (to 1 1/2" wide) in a more abundant bloom. Pennsylvania Horticultural Society Gold Medal Plant Award winner in 1995.
