Styracaceae (Snowball Family)



A small, rounded tree or shrub, two-winged silverbell or American snowdrop tree is usually multi-stemmed or low-branched. The plant grows 3–15 feet high and has alternate leaves 2–7 inches long and half as wide, with distinct veins. Deciduous leaves are dark-yellow-green in summer, changing to yellow in fall. The white, tubular flowers hang on long, pendulous pedicels and are about 1 inch across and consist of 4 waxy petals with a tight cluster of stamens in the center, looking somewhat like a white candle in a white candle holder. A two-winged fruit cures tan for fall. The bark of young trees is striped and becomes furrowed in an interesting pattern with age.

The common and scientific names both refer to the two-winged fruit. This immature sour green fruit is consumed by wildlife, including squirrels.
