Ripple Effect™ Summersweet lives up to its name by sending out ripple after ripple of sweet-smelling white blossoms throughout the summer months. Each floral spike pops against lush, deep green foliage, turning the shrub into a fragrant beacon for bees, butterflies, and admirers strolling through the garden. Its bloom performance is remarkable— abundant, sequential, and delightfully long-lasting.
This compact Clethra alnifolia tucks neatly into tight spaces without sacrificing presence. Whether placed near a porch, walkway, or patio, the perfume from its blooms drifts through warm air, creating a natural scent garden with zero effort required. As a native shrub, it fits seamlessly into pollinator gardens, woodland edges, or mixed landscapes where ecological value matters just as much as beauty.
Once autumn arrives, the show continues as the foliage takes on warm golds and ambers, adding another season of color before winter settles in. Ripple Effect™ Summersweet brings fragrance, form, and multi-season charm together in an easy-care package—a perfect choice for gardeners seeking a dependable, compact shrub that delivers sensory appeal from summer into fall.
