Phonetic: KLETH-rah al-nih-FOH-lee-ah

#1 Pot - 18-24"

Sweet Pepperbush, also called Summersweet, is easily grown in average, medium to wet soils in full sun to part shade. Prefers part shade and consistently moist, acidic, sandy soils. Soils should not be allowed to dry out. Promptly remove root suckers unless naturalized look is desired. It is noted for producing a mid to late summer bloom of sweetly fragrant white flowers. Flowers are very attractive to butterflies and bees. One interesting visitor to the late-blooming Clethra is the organ pipe mud dauber wasp (Trypoxylon politum). A nonaggressive iridescent black wasp that hunts spiders and sips nectar—what’s not to love?
