Más nevek: Summer Sweet, Clethra
Clethra alnifolia, commonly known as Sweet Pepperbush, is a deciduous shrub native to eastern North America. It features fragrant white flowers blooming in mid to late summer and thrives in moist, acidic soils.
Basic info
Sweet Pepperbush (Clethra alnifolia) is a deciduous shrub growing between 120 and 300 cm tall with a spreading, irregular crown. Its simple, oval leaves turn yellow or red in autumn. The plant produces fragrant white flowers from July to August, attracting bees and other pollinators. The fruit is a small brown capsule maturing in autumn, though it has little ornamental value.
This species prefers moist, acidic soils and tolerates wet conditions well, including occasional flooding. It grows best in partial shade but can adapt to full sun if moisture is sufficient. The growth rate is moderate, and pruning needs are low, typically done after flowering to maintain shape and encourage new growth.
Sweet Pepperbush is non-toxic to humans and pets, with no known allergenic effects. It generally requires no special winter protection, though young plants benefit from mulching in colder climates. Propagation is possible via seed sowing in early spring, softwood cuttings in late summer, or division of root suckers.
