Cinnamon clethra (Clethra acuminata)
KLETH-rah ah-kew-min-AY-tah
Genus:
Clethra
Larger in all respects than common sweet pepperbush (
Clethra alnifolia ), this sizable shrub or small understory tree grows 8 to 12 feet tall and wide. In early summer, long, slender racemes composed of small ivory flowers appear, then give way to peppercorn-shaped seed capsules that swoop out from the branch tips in fall. About the same time, lance-shaped leaves become a glowing golden yellow before falling to reveal the reddish brown bark. The bark peels in small, irregular patches in the fashion of sycamores (
Plantus occidentalis ) to expose a dusty gray under-bark. Cinnamon clethra is a good choice for a woodland garden, where the tiered branches and elegant stems look captivating against new fallen snow.
Noteworthy Characteristics:
Native to rich mountain woods and streamsides in the southern Appalachians from Pennsylvania to Georgia.
Care:
Provide full sun to light shade and moist soil. It benefits from more shade farther south.
Propagation:
Root cuttings in early summer, or start seeds in containers outdoors in spring or fall.
Problems:
Generally trouble-free, but fungal dieback and root rot sometimes affect plants.
