Clethra acuminata is a deciduous shrub that usually grows to a height of 12', occasionally to a height of 20' or more, at which point it can be considered a small tree. It is multi-branched, with a dense form, and bears abundant terminal racemes of white, bell-shaped flowers that emit a spicy, peppery fragrance. The flowers are borne mid-summer, and are followed by brown seed capsules that persist through winter.
