Summary

With its tiered branching habit, rich green foliage and abundant blooms, 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. Clethra acuminata prefers a moist, well drained, humus-rich, acid 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 Tiarella ‘Cygnet’, Leucothoe fontanesiana, Polystichum acrostichoides or Osmundastrum cinnamomeum.
