Sugartina Crystalina Summersweet

Sugartina Crystalina Summersweet

Sugartina® Crystalina Summersweet is a dwarf selection of Clethra alnifolia, the summersweet or sweet pepperbush native to wet woods and swamps of Maryland’s Coastal Plain. Where the wild shrub can reach 6–12 feet, this one forms a tight, rounded mound only 2½–3 feet tall and about as wide. Dark, glossy green leaves cover the stems to the ground, and the plant keeps its dense shape without pruning.

In midsummer, upright spikes of pure white flowers open above the leaves and fill the air with a sweet scent that carries on warm evenings. Butterflies and native bees visit the blooms, and the small brown seed capsules that follow stay on the stems into winter, where songbirds feed on them. In fall the foliage turns yellow. The compact size suits foundation beds, patio borders, low edges along walks, and large containers.

Crystalina grows in full sun to full shade, though it flowers most heavily with at least a half day of sun. Like the species, it prefers moist, acidic soil rich in organic matter and adapts to clay, loam or sand. It tolerates periodic flooding, even by brackish water, which makes it useful in low spots and near downspouts. Deer seldom browse it. A few simple steps keep it healthy and blooming.

Care Instructions:

Planting: Plant in spring or early fall where it receives morning or full sun for the most flowers, setting the top of the root ball level with the surrounding soil.
Soil: Prefers moist, acidic soil with plenty of organic matter; alkaline soil can lead to pale, yellowing leaves during the growing season.
Watering: Water deeply once or twice a week during the first season and during dry summer spells, since the roots perform best when the soil never dries out completely.
Fertilizing: If growth seems slow, apply a granular fertilizer for acid-loving shrubs in early spring, following label directions.
Pruning: Flowers form on the current season’s stems, so shape the shrub in late winter or early spring before new growth begins; heavy pruning is seldom needed.
Spacing: Space plants approximately 3–4 feet apart; because each shrub grows only 2–3 feet wide, plants will remain as separate rounded mounds with open ground between them.
Maintenance: Keep a 2–3 inch layer of mulch over the roots to hold moisture, and remove root suckers that spread beyond the intended bed.

Gardeners choose Crystalina for a native shrub that brings fragrance to the garden in midsummer, when few other shrubs bloom, at a size that fits under windows and beside patios. It performs best in moist beds with partial to full sun, and its wildlife value, wet-soil tolerance and deer resistance make it a practical choice for low-maintenance native and pollinator plantings.

Landscape Solutions:

• Its 2½–3 foot mature size fits foundation beds and under-window plantings without regular pruning.
• Tolerance of periodic flooding makes it useful in rain gardens, low spots and beds near downspouts.
• Fragrant flowers placed near a patio, deck or walkway can be enjoyed on summer evenings.
• Deer resistance helps it hold up in neighborhoods where browsing damages other shrubs.
• Its compact, rounded form works as the upright centerpiece of a large mixed container.
