Symphoricarpos orbiculatus aka Round Snowberry

Symphoricarpos orbiculatus is a deciduous shrub known as coralberry. It belongs to the honeysuckle family, Caprifoliaceae. Its native range spans the central and eastern United States. It also reaches northeastern Mexico. It grows in woods, thickets, fields, and dry banks. Garden plants reach 2–5 feet [0.6–1.5 metres] tall. They spread 3–8 feet [0.9–2.4 metres] wide. Some plants reach 6 feet [1.8 metres] in height. Arching stems give the shrub a low, rounded shape. Underground stems and suckers can build dense colonies over time.

Older branches have brown bark that peels in loose strips. Young stems bear short hairs and turn reddish brown. Pairs of simple, oval leaves grow along the stems. Their upper sides range from green to blue-green. The paler undersides may bear fine hairs. Leaf edges are mostly smooth and may curl under. The leaves can turn red or burgundy in fall. This fall color adds interest before the branches become bare.

Small bell-shaped flowers form where leaves meet the stems. Short spikes also grow at the branch tips. The blooms range from greenish white to pale pink. Flowering can run from May through August, depending on conditions. Bees, wasps, and flies visit the flowers for nectar. Round, berry-like drupes ripen in clusters during fall. Their colors range from coral red to reddish purple. Each drupe holds two seeds. The fruit can stay on branches through much of winter. Plants need more than one genetic strain to set fruit.

Coralberry grows in sun or partial shade and tolerates deeper shade. It accepts clay, loam, sand, and rocky soils. It also grows across acidic, neutral, and alkaline soils. Moist soil with good drainage suits it well. Once growing, it tolerates dry soil, drought, heat, and compaction. Chicago lists USDA zones 2–7; RHS gives a UK rating of H6. Gardeners use it for loose hedges, woodland planting, and slope cover. Its spreading roots help hold soil on banks. Remove suckers and runners where spread would cause problems. Birds and small mammals use it for food and shelter. Moths also use it as a host plant.

Serious pest and disease problems are not usual. Aphids and leaf-feeding insects can damage the foliage. Leaf spots, anthracnose, mildew, rust, and stem galls may occur. Honey fungus is a rare risk. Reports differ on deer resistance; deer may browse it heavily. The fruit can cause vomiting and diarrhea if eaten. PFAF records limited food use, but also advises caution. Treat it as ornamental fruit, not a garden snack. PFAF also records past use of bark and leaf eye washes. That record does not establish safety or benefit.
