Clethra alnifolia 'Sixteen Candles'

Sixteen Candles Summersweet is a compact native shrub prized for its upright white flower spikes, sweet fragrance, and excellent pollinator appeal. Unlike older Clethra varieties that can appear loose or sprawling, Sixteen Candles features a more upright, refined habit that fits beautifully into foundation plantings and smaller landscapes. Blooming in mid to late summer, it provides fragrance and color when many shrubs have finished flowering.

  • Fragrant upright white flower spikes
