Description

Sweet Pepperbush, Clethra alnifolia, also called Summersweet, is a deciduous shrub that is native to swampy woodlands, wet marshes, stream banks and seashores, often in sandy soils, along the coast. It is a rounded, suckering, densely-branched, deciduous shrub that typically grows to 3-6 feet tall and is noted for producing a mid to late summer bloom of sweetly fragrant white flowers which appear in narrow, upright panicles. Flowers give way to dark brown seed capsules (1/8-inch diameter) which may persist into winter. Mature stems have scaly, dark gray to brown black bark. Serrate, obovate to oblong, glossy dark green leaves turn variable but generally attractive shades of yellow to golden brown in fall.

Easily grown in average, medium to wet soils in full sun to part shade. Prefers part shade and consistently moist, acidic, sandy soils. Soils should not be allowed to dry out. Tolerates clay soils. Tolerates full shade.
