Clethra alnifolia ‘Sixteen Candles’ is a compact and very elegant ornamental shrub, renowned for its fragrant summer flowering and its narrow habit perfectly suited for small gardens. This selection stands out for its upright, white, and very straight flower clusters, reminiscent of candles, which appear in abundance in mid-summer. Its dark green deciduous foliage superbly highlights the blossoms, then turns golden yellow in autumn, extending its decorative interest. Highly valued for borders, beds, foundation plantings, and naturalistic gardens, it attracts numerous pollinating insects. Tolerant of moist and even waterlogged soils, Clethra alnifolia ‘Sixteen Candles’ is extremely hardy and perfectly suited to Quebec conditions, while offering a neat and easy-to-integrate silhouette.
