Coast Snowball Styrax grandifolius

Phonetic Spelling
STYE-racks gran-dih-FOH-lee-us
Description

Styrax grandifolius, commonly known as Bigleaf Snowbell is a deciduous tree native to North Carolina. In nature, it can be found in mesic to dry upland hardwood forests, on rocky slopes, and in ravines.  It forms thickets. Commonly found as an understory tree in mature hardwood forests. 

Its white, bell-shaped flowers form as racemes, each having 5 to 20 flowers.  Some images indicate that the flowers may be partially concealed by its large leaves.  When in full bloom, this is not the case.  The showy flowers are quite visible.

It's said that this plant will perform better when grown in the garden than what is found in the wild.  A controlled environment or location will allow the plant to flower at its best.  In the wild, optimum conditions cannot be guaranteed.  A heat loving specimen, growing in climates that experience cooler summers may also lead to a less than successful habit.

Named for its very large leaf.  It can be easily propagated by leaf cuttings.  It is classified as a FACU, a Facultative Upland species meaning it rarely occurs on wetlands. 

Insects, Diseases, and Other Plant Problems:  No serious insect or disease issues.
