Halesia carolina 'Rosea': 'Rosea' Carolina Silverbell1

Edward F. Gilman and Dennis G. Watson 2


A North American native tree, Carolina Silverbell grows into a 20 to 40-foot-tall tree with a 15 to 30-foot-spread into a pyramidal silhouette. The two to four-inch-long leaves turn yellow in fall and are among the first to drop in autumn. The tree prefers sandy loam and begins blooming when only 10 to 12 feet tall. The pink, bell-shaped, showy blossoms are borne in two to five-inch-long clusters. Flowering occurs along last years branches in mid-May on the previous season's wood. Because the flowers point downward, they are partially hidden by the foliage and best viewed from below. Other ornamental features are the yellow fall color and the bark, which peels off in large, flat scales. The pale yellow fruits are quite attractive as they hang down from last year's branches. Carolina Silverbell may transplant poorly in the fall.

Use and Management

This tree is interesting all year long, with attractive medium green foliage, pretty flowers, showy fruits, and exfoliating bark. It branches low to the ground, making a nice lawn or specimen tree and when pruned to one central leader can be used as a street tree in residential areas. The bark shows off nicely with foliage removed from the lower branches, and multi-stemmed specimens come-to-life when lit from below at nighttime. They would make a perfect small-sized tree for planting near a deck or patio.

An understory tree best suited for a partially shaded or shaded location, Silverbell prefers moist, fertile soil with an accumulation of leaf litter and/or mulch. The tree grows best if roots are not confined to a small area and are allowed to explore a large soil area. Water during a drought and avoid compacted soil.

Propagation is by seeds sown as soon as ripe or stratified, and by layering, root cuttings, and greenwood cuttings. Small trees and seedlings transplant easily.

Pests and Diseases

No pests or diseases are of major concern.
