The Morton Arboretum
Tree 5 - 10 m tall, trunk 15 - 30 cm in diameter Leaves: opposite, clustered near end of stem, dark green above, paler beneath, 7 - 12 cm long, 5 - 8 cm wide, elliptic to egg-shaped with arching (arcuate) veins, non-toothed or wavy-toothed, sometimes hairy above, often hairy along veins beneath. Leaves turn red to reddish purple in fall. Flowers: borne at ends of stems in tight clusters, yellowish green. Four showy, white to pinkish, petal-like bracts to 5 cm long surround the flowers. Fruit: fleshy with one or two center seeds (drupe), in clusters of three to six, shiny red, 1 - 1.5 cm long, egg-shaped. Bark: reddish to blackish brown, broken into squared plates. Twigs: changing from yellowish green with white hairs to smooth and light brown or reddish gray, arching upward at the tips. Buds: green to red, tiny, narrow, hairy. Flower buds are stalked, grayish, flattened spherical, and silky. Form: flat-topped, wide-spreading, with a short crooked trunk that divides close to the ground.

Similar species: Cornus florida has the arching leaf venation characteristic of the genus. It is easily distinguished from other dogwoods because it is a small tree that has four large petal-like bracts surrounding the flower clusters and tight clusters of red fruit.

Flowering: late April to early June

Habitat and ecology: An understory tree frequently found in mesic woods of the eastern Chicago Region.

Occurence in the Chicago region: native

Notes: This species is a commonly planted ornamental tree with many cultivars available, including some with pink or red flower bracts. The wood is used for making tool handles, bobbin heads, weaving shuttles, mallet heads, and spools. Extracts made from the bark and flowers were once treatments for fever, jaundice, cholera, and malaria. The leaves decompose quickly, are high in calcium and enrich the soil efficiently.

Etymology: Cornus comes from the Latin word, cornu, meaning horn, referring to its hard wood. Florida comes from the Latin word for flowering, referring to its large flowers.
