Clethra alnifolia - Summersweet, Sweet Pepperbush
Summersweet (Clethra alnifolia), also known as Sweet Pepperbush, is a beloved native shrub that fills the late summer garden with an irresistible sweet fragrance. Dense spikes of white flowers bloom from mid to late summer — a season when few other shrubs are in flower — drawing in bees, butterflies, and hummingbirds in abundance. The glossy dark green foliage turns beautiful shades of yellow to golden brown in fall, and the ornamental seedpods persist through winter for additional interest. A highly adaptable native, Summersweet thrives in moist to wet soils and tolerates both shade and full sun, making it an excellent choice for rain gardens, woodland edges, and naturalized areas.
