Itea virginica aka Tassel White

Itea virginica, or Virginia sweetspire, belongs to the Iteaceae family. This shrub is native to the central and eastern United States. Its range runs from New Jersey south to Florida. It extends west to Missouri, Louisiana, and eastern Texas. Wild plants grow in damp woods, swamps, and wet pine barrens. They also grow beside small streams. Most plants lose their leaves, though some keep part of them.

Garden plants reach 3–6 feet [0.9–1.8 metres] tall and wide. Some sources give a smaller range of 3–5 feet [0.9–1.5 metres]. Plants can reach 8 feet [2.4 metres] in good conditions. Several stems rise from the base, then bend into arches. Root suckers let the shrub spread into thick groups. Smooth bark turns brown and develops splits with age. Young stems stay green but turn red-purple on their sunny side. The simple, oval leaves grow in an alternate pattern. Their edges have fine teeth, and their upper faces are smooth. Green leaves turn red, orange, gold, or purple in fall. Some leaves stay on the stems into early winter.

Small white flowers grow in hanging clusters called racemes. Each cluster measures about 0.25–0.5 feet [0.08–0.15 metres] long. The flowers have a light scent and open from base to tip. Reports place bloom between May and August, depending on location. Flowers form on wood grown the year before. Butterflies and other pollinators visit them. Slim, brown, woody capsules follow in late summer and fall. They hold tiny seeds and can last through winter. Songbirds eat the seeds. NC State lists the fruit as edible and tags the seeds as edible.

Grow sweetspire in sun or part shade. It tolerates deep shade, but sun improves bloom and fall color. Moist, fertile, acidic soil suits it best. It also tolerates clay, wet ground, brief floods, and dry spells. Sources place it in USDA zones 5–9. Cold below minus 20°F can cause problems. Prune after bloom to protect next year's flower buds. Remove unwanted suckers where spread would crowd nearby plants.

Use this shrub in borders, hedges, or loose woodland groups. It also suits rain gardens and stream or pond edges. Its suckers help hold soil on slopes. Care needs are low, and serious pests or diseases are uncommon. Deer tend to leave it alone. NC State reports resistance to Phytophthora root rot. Alkaline soil can cause chlorosis, leaving the leaves pale.
