plant sale text: Mountain Sweet-pepperbush produces spicily-scented small white flowers in the summer. This species also shows beautiful gold fall color. This southeastern native shrub grows primarily in moist acid soils along streambanks in the mountains. This species has a more upright growth habit than other clethras, as well as being tolerant of more well-drained soils. It also features attractive peeling cinnamon-brown bark as it matures. Mountain Sweet-pepperbush can be grown as a shrub or a small tree, limbed up in order to accentuate its handsome bark.
