Clethra acuminata: Cinnamon Clethra for Woodland Gardens

Clethra acuminata – Large Native Shrub with Peeling Bark

Larger than sweet pepperbush, this sizable shrub/small understory tree grows 8–12 feet tall and wide. Long slender racemes of small ivory flowers in early summer, then peppercorn-shaped seed capsules in fall. Lance-shaped leaves turn glowing golden yellow before falling, revealing reddish-brown bark peeling in sycamore-like patches to expose dusty gray under-bark.

Culture

Full sun to light shade, moist soil. Benefits from more shade farther south. Propagate by root cuttings early summer or seeds in containers outdoors spring/fall. Generally trouble-free; fungal dieback and root rot sometimes affect plants.

Outstanding Features

Native to rich mountain woods and streamsides in southern Appalachians (PA to GA). Good for woodland gardens where tiered branches and elegant stems captivate against snow.
