Clethra alnifolia ‘Hummingbird’ is a compact and very floriferous ornamental shrub, appreciated for its fragrant summer flowering and its excellent adaptation to moist soils. This dwarf selection forms a dense and rounded habit, ideal for small gardens, borders, and plantings in cool or poorly drained areas. In summer, it is abundantly covered with upright clusters of small, intensely fragrant white flowers, rich in nectar, which strongly attract pollinating insects. Its deciduous dark green foliage turns beautiful golden yellow in autumn, extending the plant's decorative interest. Very hardy and perfectly adapted to Quebec conditions, ‘Hummingbird’ stands out for its generous flowering, its manageable size, and its ease of cultivation.
