Clethra alnifolia Rosea is one of the best native shrubs for American gardens! Fragrant, late-summer flowers (attractive to butterflies) adorn handsome, deep-green foliage that ignites into flaming yellows and oranges in fall.

Rosea has been exceptionally popular for many years because of its unusual pink-blushed flowers. This plant reaches 4 to 6 feet tall and wide. Dense, compact and somewhat rounded in habit, it possesses a trouble-free disposition. Remarkably pest- and disease-free, it prefers a moist, slightly acidic, sandy soil in sun or light shade, although it tolerates heavy soils and dense shade.

This hardy Summersweet is ideal for large massing and excellent as a foundation plant, especially for problem wet spots and late-summer color when little else is in bloom. Very hardy. Zones 3-9.
