Clethra Alnifolia Hummingbird #3
Clethra alnifolia ‘Hummingbird’ is a compact, deciduous shrub prized for its fragrant, pure white flowers that bloom in mid to late summer. The flowers are borne in upright, bottlebrush-like spikes along the branches, attracting hummingbirds, bees, and butterflies, making it highly valued for wildlife gardens. ‘Hummingbird’ has a naturally dense, rounded habit with medium-green, glossy foliage that turns yellow to golden in fall, adding seasonal interest. Its compact size and tidy growth habit make it ideal for small gardens, foundation plantings, borders, or mixed shrub beds, providing both ornamental beauty and pollinator-friendly value.
