Vanilla Spice® Summersweet Bush

Introducing the Vanilla Spice® Summersweet (Clethra alnifolia), an enchanting native shrub that blooms with extra-large, fragrant white flowers during the summer. These blooms aren't just a treat for the eyes; their sweet scent is a delightful aroma that's best enjoyed near patios and decks during the mid-summer season.

Uniquely, the Vanilla Spice® stands out from other varieties with its significantly larger individual florets, approximately double the size of typical summersweets. This dense, deciduous shrub typically grows between 3-6 feet, occasionally reaching up to 8 feet. Its upright panicles showcase the flowers, which later give way to dark brown seed capsules that can persist into winter, adding interest even in colder months.
