Sweet pepperbush (Clethra alnifolia) is a shrub prized for its spikes of fragrant white flowers that attract a wide variety of pollinators, including bees and butterflies, during the summer. It can reach about 1.5 meters in height, forming thickets thanks to its suckering roots. This shrub is particularly well adapted to moist soils, making it an excellent choice for garden borders, wet areas, or near bodies of water. It is highly resistant to difficult conditions, including Quebec winters, up to zone 4, and is remarkably free from diseases, insects, or physiological problems. Its dried fruit capsules, which persist long after flowering, are a source of interest for seed-eating birds, thus extending the ornamental and ecological utility of the plant after the blooming season.

Ecological Roles
Sweet pepperbush plays an important role in the ecosystems where it is introduced, particularly in Quebec. Its fragrant flowers are an important source of nectar for bees and butterflies, while its dried fruit capsules feed seed-eating birds after flowering. Thanks to its suckering roots, this shrub also helps stabilize moist soils, making it an ideal plant for preventing erosion in marshy environments. Furthermore, its ability to form dense thickets makes it a refuge for small wildlife. Resistant to diseases and requiring no intensive maintenance, this shrub is a safe bet for naturalist gardens and ecological landscaping.
