Overview

Itea virginica, Virginia sweetspire, is a deciduous to semi-evergreen shrub in the family Iteaceae, growing 3-5 feet (90-150 cm) tall and 3-6 feet (90-180 cm) wide with arching branches. From late spring into early summer it produces drooping, cylindrical clusters of small, fragrant white flowers 3-6 inches (8-15 cm) long. The oval leaves are 2-4 inches (5-10 cm) long, medium green in summer, turning shades of red, orange, and purple in fall and often holding late into the season or through winter in mild climates. The shrub spreads by suckers to form colonies and grows naturally along streambanks, swamps, and moist woods in the southeastern United States. It tolerates wet soils and short flooding but also adapts to average garden conditions, declining only on very dry sites. Its suckering habit can make it spread wider than expected in moist ground. I. virginica is grown in rain gardens, shrub borders, pond edges, and mass plantings for its flowers and fall color.

Native Range

Itea virginica is native to the southeastern United States, from New Jersey south to Florida and west to Texas and Missouri. It grows along streams, in swamps, and in low, moist woodlands. It is most common on the coastal plain.

Suggested Uses

Virginia sweetspire is planted in rain gardens, pond and stream edges, shrub borders, and mass plantings on moist ground. It is used for erosion control on damp slopes and streambanks. Its flowers draw bees and butterflies, and the fall foliage extends seasonal color.

How to Identify

Identify Virginia sweetspire by its arching stems and drooping, bottlebrush-like clusters of small white flowers in late spring. The simple, finely toothed oval leaves turn red to purple in autumn and often persist into winter. The stem pith is white and chambered. Its drooping white racemes and late, lasting fall color separate it from summersweet (Clethra alnifolia), which has upright flower spikes.

Care & Maintenance

Care Guide

Grow Virginia sweetspire in full sun to part shade in moist, fertile soil; it accepts clay, loam, and sandy soils that stay damp. It tolerates wet ground, periodic flooding, and pond margins, and grows in average garden soil with regular water. Fall color is strongest in more sun, while plants in shade flower and color less. It is hardy in USDA zones 5-9 and suckers freely, forming broad colonies in moist sites. Cut back or divide suckers to control spread. It has few pests and diseases, though chlorosis can appear on dry, alkaline soils.

Pruning

Prune right after flowering, since flower buds form on the previous season wood. Remove the oldest stems at the base every few years to renew the shrub. Dig or cut suckers to limit the spread of the colony.
