Clethraceae
Clethra alnifolia ‘Pink Spires’ is an elegant ornamental shrub highly prized for its fragrant summer bloom in delicate pale pink hues. It forms a dense, rounded shrub, perfectly suited for beds, informal hedges, and naturalistic gardens, especially in moist or cool soils. In summer, it is covered with long, upright clusters of soft pink flowers, rich in nectar, which abundantly attract pollinating insects and add a soft and refined touch to the garden. Its deciduous dark green foliage turns beautiful golden-yellow shades in autumn, extending the decorative interest at the end of the season. Very hardy and well adapted to Quebec conditions, Clethra alnifolia ‘Pink Spires’ is easy to cultivate and is an excellent choice for combining fragrance, color, and ecological value.
