Estimated Native Range
Summary
Cornus rugosa, commonly known as Roundleaf Dogwood, is a deciduous shrub native to cool, moist, deciduous and mixed forests in the Eastern United States and Canada. It typically grows 1–4 m (3–13 ft) tall and is notable for its yellowish-green twigs, which may display red or purple blotches. The leaves are broad and round, contributing to its common name. In early summer, Roundleaf Dogwood produces flat-topped clusters (cymes) of small, white, pedunculate flowers with four calyx lobes and four petals, each cyme measuring 3–6 cm (1+1⁄4–2+1⁄4 in) wide and containing 20–50 flowers. By October, it bears blue to greenish-white drupes that are attractive to birds.
This shrub is valued for its understated beauty and its ability to thrive in shaded conditions, making it suitable for woodland gardens, naturalized areas, and shaded borders. It is also used for erosion control due to its dense root system. Roundleaf Dogwood is adaptable to a range of soil types, though it prefers well-drained to normal moisture soils. It can tolerate full sun to partial shade, with lower water requirements once established. While generally low-maintenance, it can be susceptible to dogwood anthracnose and borer insects.CC BY-SA 4.0
