Clethra Shrubs

About

Turn damp areas into fragrant garden moments. Clethra is a go-to solution shrub for beds that stay evenly moist, low spots, downspout-adjacent borders, rain-garden edges, and woodland margins where many flowering shrubs struggle.

Many regions see clethra peak in mid-to-late summer (commonly July through early August in warmer areas), which helps keep borders interesting after early-season shrubs are done and before fall color fully arrives. Mature size depends on cultivar, but summersweet clethra is often listed around 5–8 feet tall and 4–6 feet wide for common forms, with a rounded, shrub-like habit that fills space without constant shearing. Many selections also deliver attractive fall foliage color (often yellow to golden tones), adding another season of interest. Plant it where moisture and light cooperate. Clethra is happiest in moisture-retentive, acidic-t
