Clethra alnifolia 'Hummingbird' (Sweet Pepperbush 'Hummingbird') is a compact selection of summersweet that brings big seasonal interest to smaller spaces. You get upright, bottlebrush-like spikes of fragrant white flowers in mid to late summer, a time when many shrubs are finished for the year. The blooms are a reliable draw for butterflies and hummingbirds, and the tidy habit makes it easy to tuck into mixed beds and borders.
Plant it where you can enjoy the scent, near a walkway, patio, or along the edge of a seating area. It performs best in full sun to part shade; in warmer areas, a little afternoon shade can help keep the foliage looking fresh. This shrub is especially useful in spots that stay consistently moist, and it also tolerates damp soils better than many flowering shrubs.
Expect a mature size around 36-48 inches tall, with a rounded, lightly spreading form as it fills in. Give it room to develop its natural shape, and keep mulch over the root zone to conserve moisture and even out soil temperatures. Water regularly during the first growing season; after establishment, maintain even moisture for the best flowering and overall vigor.
Pruning is usually minimal. If you need to shape or reduce size, do it in late winter to early spring before new growth starts. Because it flowers on new growth, fresh spring growth supports that summer bloom display. Pair it with other moisture-friendly perennials and shrubs for a layered planting that looks good from spring through fall.
