To see Styrax japonicus properly you have to look up. The leaves ride along the tops of the branches, all turned to the sky, while underneath, in late spring, hang rows of small white bells on slender stalks, so the whole horizontal tier of the tree seems lit from below. Stand beneath one in bloom and the common name explains itself.
American snowbell is one of the quiet delights of the Southeastern wetlands, usually a graceful multi-stemmed deciduous shrub, though the plant can be trained up into a small single-trunked tree. Along streamsides and in low, wet ground from the coastal plain through the interior South, the shrub carries slender branches that hang, in spring, with rows of small, bell-shaped white flowers, faintly fragrant and nodding on fine stalks so the whole plant seems trimmed in tiny lanterns.
Styrax obassia, the fragrant snowbell, is the bold-leaved cousin of the more familiar Japanese snowbell, a small deciduous tree from the mountain woodlands of Japan, Korea, and China. Where Styrax japonicus hides small bells beneath fine, layered branches, the fragrant snowbell wears large, rounded, almost tropical leaves up to eight inches across, and hangs long, drooping chains of white, bell-shaped flowers that carry a sweet perfume through the late-spring garden.
