Styrax americanus aka American Snowbell

Styrax americanus, or American snowbell, belongs to the Styracaceae family. This deciduous shrub can also form a small tree. Its native range covers the southeastern and east-central United States. It grows from Florida west to eastern Texas. Its range extends north to Virginia, southern Illinois, and southern Indiana. Wild plants grow in swamps, wet woods, and along streams. Some grow in standing water at wetland edges.

Garden plants reach 6–10 feet (1.8–3.05 metres) tall and wide. Some reach 15 feet (4.6 metres) in height. Growth is slow, and the crown is broad and open. Slender branches grow from the base and along the trunk. The roots do not produce suckers. Young bark is thin, smooth, and dark gray. Cracks form in the bark as it ages. Slender, gray-brown twigs bend in a zigzag pattern. Their early hairs fall away as the twigs mature.

The simple leaves grow in an alternate pattern along stems. They are oval to egg-shaped, with toothed edges. Bright green, glossy leaves reach three inches long. Some leaves carry a few hairs. Fall leaves may turn yellow, brown, or copper. Their autumn display is modest. White flowers hang from the branches in April and May. Each bell-shaped bloom has five bent-back petals and yellow stamens. Flowers appear alone or in groups of up to four. Each measures less than an inch across and has a sweet scent. Small, hairy fruits follow the flowers and mature in fall. These nearly round fruits turn gray-brown and measure about one-third inch long.

Grow American snowbell in sun or partial shade. It needs rich, acidic soil with enough drainage. Sandy loam suits it well, and it tolerates wet ground. Keep the soil moist, with ample water in sunny sites. It grows in USDA hardiness zones 6–8. Avoid crowding it among other plants, where it grows poorly. Prune in winter when shaping is needed. Propagate it from cuttings or seed. Seeds need a cold, moist period before they sprout.

Use this shrub in wet garden areas or woodland plantings. It can stand alone or form a loose screen. Small groups also suit the back of a border. A patio nearby gives access to the flowers' scent. Bees, butterflies, and moths visit the blooms. The plant hosts Promethea silkmoth larvae, and its fruits attract birds. Missouri Botanical Garden reports no major insect or disease problems.
