Cornus rugosa, commonly called roundleaf dogwood, is a deciduous tree native to the eastern United States and Canada.
Cornus rugosa is a shrub or small tree, 1-4m tall, with yellowish-green twigs that may have red or purple blotches. Pith is white. Leafs are oppositely arranged, round orbicularly shaped with an acuminate tip, have an entire margin, and are woolly to hairless below. Leafs have 6-8 pairs of lateral veins and 7-15cm long. Leaf scars are broadly U shaped with 3 bundle scars.
White flowers appear in early summer arranged on flat topped cymes. The flowers themselves are pedunculate with 4 calyx lobes and 4 petals. The cymes are 3-6cm wide and contain 20-50 flowers. Fruits are blue to greenish white drupe that matures in October.
Roundleaf dogwood prefers well drained to normal moisture soil and, like most dogwoods, is shade tolerant.
