Clethra

Clethra

Clethra is a deciduous shrub prized for its fragrant summer blooms and attractive foliage. Commonly called summersweet, this plant produces elegant spikes of white or pink flowers from midsummer to early fall. Each fragrant blossom draws bees, butterflies, and hummingbirds, making Clethra a valuable addition to pollinator-friendly gardens. Its glossy green leaves often turn golden-yellow in fall, providing multi-seasonal interest beyond the flowering period.

Compact and versatile, Clethra thrives in woodland-style gardens, along borders, or near foundations where it can provide both beauty and structure. The shrub’s natural, rounded habit blends well with perennials, other shrubs, and ornamental grasses. It adapts to a variety of soils but performs best in moist, acidic, and well-draining locations. Clethra is low-maintenance, disease-resistant, and offers reliable performance year after year, making it an ideal choice for gardeners seeking both fragrance and visual appeal.

Care Instructions

Planting

Plant in full sun to partial shade. Choose well-draining soil enriched with compost. Space plants to allow airflow and room for mature growth.

Watering

Keep soil consistently moist, especially during the first growing season. Water deeply in dry spells to encourage strong root development.

Pruning

Prune lightly after flowering to maintain shape and remove spent blooms. Remove any dead or weak branches in early spring.

Pest Control

Clethra is generally pest-resistant. Monitor for aphids or scale insects and treat with insecticidal soap if needed.

Soil Tips

Prefers acidic, moist, well-draining soil. Mulch around the base to retain moisture and keep roots cool. Avoid compacted or waterlogged conditions.
