These aromatic and lively shrubs turn compact areas like walkways and gardens into generous displays of tall white, flowering candles hoisting themselves above a lush, green shrub. Full of nectar, your neighboring butterflies will make your enticing summersweets their new home. As a deciduous perennial, it bursts with a beautiful yellow just as the fall season sets into winter. The botanical name for 16 Candles Summersweet is Clethra alnifolia 16 Candles, which is best grown in full sun to partial. This fragrant shrub has green, toothy leaves with candlestick flowers that rise from foliage in the summer to bloom white, nectar-rich flowers, which tend to attract nearby butterflies. Between their pleasant fragrance and wildlife attracting flowers, these are an ideal addition to any garden, yard, border or walkway.
