Clethra alnifolia, known as summersweet, or sweet pepperbush is a native, deciduous upright shrub that typically grows between 4 and 8 feet tall and slowly spreads by sending up new shoots from rhizomes to form a small thicket. The species or taller selections can be grown as low hedges or as back of the garden border plants. Smaller cultivars combine well with perennials in the garden. It is tolerant of both, infertile or acid, wet and dry soils.
Use as specimen shrub or woodland gardens. Valued for summer blooming fragrant white spirelike clusters. Different varieties such as "Hummingbird ", "Ruby Spice, "Rosea", "Sixteen Candles", and "September Beauty" are variously available.
