Description

American snowbell is a native small tree or large shrub in the Styracaceae (silver bells) family.  This slender branched woody ornamental is native to the southeastern US and can be found growing in swamps, marshy areas, stream banks, and other wet locations. 

Plant in full sun to partial shade in rich, acidic, well drained sandy loam based soils.  It is tolerant of wet soils.  When mature it reaches a height and width of 6 to 10 feet with a wide, open crown and dense, uniform branches that originate from the base and up the main trunk.  In the spring pendulous rounded clusters or single bell-like blooms of white flowers exude an aura of sweet fragrance that attracts pollinators like bees, butterflies, and moths.   After flowering has completed, hairy fruits emerge.  American silverbells does not sucker from the roots. 

This plant can be propagated by stem cuttings.  To propagate by seed, once the seed has turned a glossy brown and the capsule has begun drying, collect the seed and store in a sealed container under refrigeration.  Seed collected from the ground is not recommended for propagation.

Use this flowering small tree or shrub as a specimen in wet areas of the landscape in a woodland garden, or in small groups as a backdrop to a border or for screening.  Planting it near a patio will ensure the enjoyment of the fragrant blooms.

Host to Promethea silkmoth (Callosamia Promethea)

Insects, Diseases, and Other Plant Problems:  This plant does not do well when situated in tight conditions with other plants. It will do fairly well in full sun as long as adequate water is supplied.
