Introducing Clethra tomentosa, commonly known as the Woolly Summersweet, Coastal Pepperbush, or Downy Sweet Pepperbush—a captivating deciduous shrub delighting native plant enthusiasts and wildlife alike. Originating from the southeastern U.S., this shrub graces gardens with its striking white, fragrant flowers during late summer. These blooms, flourishing on woolly spikes up to 6 inches long, create a stunning spectacle against the backdrop of dark green foliage, inviting butterflies, hummingbirds, and other pollinators to your outdoor space.

Growing to a height of 6-8 feet and a width of 6 feet, Woolly Summersweet is versatile for borders, screens, or as a standalone specimen plant. Adaptable to various conditions, including shade and damp soils, this shrub thrives in partial sun and thrives as an understory plant. The deciduous leaves, obovate and finely toothed, offer interest throughout the season, turning vibrant yellow in autumn before falling. Notably, it flowers on new wood, so a late winter prune ensures a bountiful bloom.

Ideal for moist, sandy, or clay soils, Woolly Summersweet is a hardy choice for naturalistic plantings, forming attractive colonies through its colonial root suckers—prune for a more formal appearance. Highlight your landscape with a living piece of southeastern flora that is as beautiful as it is beneficial—an alluring addition to any garden seeking both form and function.
