Tree to 4 m tall, trunk to 30 cm in diameter Leaves: opposite, 4 - 9 cm long, 3 - 4.5 cm wide, elliptic to narrow egg-shaped with arching (arcuate) veins, non-toothed, hairs rough above and soft beneath. Flowers: borne in loose, round-topped clusters, each with four thin, white petals. Fruit: fleshy with one or two center seeds (drupe), borne on red stalks, white, 6 - 8 mm wide. Bark: reddish brown, shallowly furrowed and scaly. Twigs: brown to purplish or gray, smooth or slightly hairy. Buds: egg-shaped, flattened, pointed, hairy.

Similar species: Cornus drummondii has the arching leaf venation characteristic of the genus. It can be distinguished from other dogwoods because it is a tree that blooms from late June to early July, has brown to purplish or gray stems, leaves with rough hairs above and soft hairs beneath, and clusters of white fruit on red stalks.

Flowering: late June to early July

Habitat and ecology: Fields, meadows, and along the edges of woods and prairies. This species used to be rare in the Chicago Region. It is planted in landscapes to prevent soil erosion, and now many spontaneously occurring specimens are actually escapes.

Occurence in the Chicago region: native

Notes: Tool handles are made from the strong wood. Birds and small mammals use the tree for food and shelter.

Etymology: Cornus comes from the Latin word, cornu, meaning horn, referring to its hard wood. Drummondii is named after Scottish plant explorer, Thomas Drummond (1780 - 1835).
