Clethra alnifolia 'Sixteen Candles'

Summersweet

Clethra alnifolia 'Sixteen Candles' holds its highly fragrant flowers upright like candles on a birthday cake, thus the name. Panicles of white flowers, 4 to 6 inches long, bloom from late June into July. Thrives in moist to wet soil, but will tolerate drought as well. Dense, compact habit makes it good for small gardens. Effective in mass, mixed into perennial borders or along foundations. Grows well in wet areas. Deciduous. Attractive to butterflies!


Summersweets are somewhat unique among flowering shrubs because of their ability to bloom in shady locations in late summer when few other shrubs are in bloom. Mass or group in lawns, foundations or shrub borders. Good flowering shrub for shade or woodland gardens. Effective as a hedge. Also appropriate for moist soils along stream banks or pond/water garden peripheries. Also may be naturalized in cottage gardens, wild gardens or naturalized areas. Plant near a patio to enjoy the fragrant late summer bloom. Compact size makes this an ideal flowering shrub for smaller gardens.
