Clethra acuminata

Native Plants

Cinnamon Clethra

5 Photos


With its tiered branching habit, rich green foliage and abundant blooms, cinnamon clethra (Clethra acuminata) is an ideal plant for small landscapes. This small deciduous tree or multi-stemmed shrub is suitable as an understory plant in rich, acid woodlands. Cinnamon clethra will grow 6-12’ tall and with age its outer bark exfoliates to reveal a cinnamon-colored inner bark. The small white flowers bloom from mid-July to August, are borne on 3-8” long spires, and open from the base to the tip. Cinnamon clethra prefers a moist, well drained, humus-rich, acidic soil but will adapt to drier sites. Cinnamon clethra is tolerant of shady conditions though it flowers best with more sun. Combine this species with a groundcover of Cygnet foamflower (Tiarella‘Cygnet’), drooping leucothoe (Leucothoe fontanesiana), Christmas fern (Polystichum acrostichoides) or cinnamon fern (Osmundastrum cinnamomeum). Zones 5-8.
