Shrubs, to 5 m, flowering at 0.7 m; rhizomes present. Stems solitary, 2–10 dm apart; bark gray, brittle, verrucose, frequently forming small plates; branchlets pinkish brown, turning green-maroon, and later gray-maroon, 2 proximal internodes densely pubescent, distal internodes sparsely appressed-hairy; lenticels pale lenticular spots on new growth, uniformly scattered, especially on the distal internodes, protruding and extruding corky tissue on 2d year branches; pith white in 1st year branches, brown in older branches. Leaves: petiole 2–8 mm; blade lanceolate to ovate, 1.5–8 × 0.5–4 cm, base cuneate, apex acuminate to obtuse, abaxial surface pale green, adaxial surface green, turning maroon in full sun, both surfaces with hairs appressed, white to ferruginous; secondary veins 3–4(–5 on some sucker shoots) per side, evenly spaced. Inflorescences usually elongate, sometimes convex or pyramidal, 2.5–5 cm diam., peduncle 20–40 mm; branches and pedicels yellow-green, turning bright red. Flowers: hypanthium appressed-hairy; sepals 0.2–0.5 mm; petals white, 2.3–3 mm. Drupes usually white, occasionally pale blue, oblate-ellipsoid, laterally compressed, 4–8 mm diam.; stone oblate-ellipsoid, 3–6.5 mm diam., smooth, apex rounded to slightly pointed. 2n = 22.

Cornus racemosa, much like C. foemina and C. obliqua, has a coronulate or minutely papillate abaxial leaf surface, visible under high magnification. Cornus gracilis may be a hybrid between C. racemosa and C. foemina. Hybrids between C. obliqua and C. racemosa and C. rugosa are discussed under those species.
