Shrub to 1 m tall Leaves: opposite, 2.5 - 8 cm long, egg-shaped to oblong egg-shaped, coarsely round-toothed, thick, leathery, slightly hairy beneath. Flowers: stalkless in dense, short spikes. Corolla lobed, pale pink, 5 - 9 mm long, urn-shaped. Lobes about equal to tube. Style exserted from the corolla. Fruit: berry-like (drupe), in dense clusters, white to greenish white, 6 - 10 mm long. There are two stones inside each drupe. Twigs: finely hairy when young.

Similar species: Symphoricarpos albus is similar but has stalked flowers with styles included within the corolla. Symphoricarpos orbiculatus is also similar but has smaller, greenish to purplish corollas (to 4 mm long) and drupes that are coral-pink to purple.

Flowering: mid-June to late August

Habitat and ecology: Possibly introduced from farther west. Locally frequent in dry open ground, particularly in loose railroad ballast. Rarely seen in stable native communities.

Occurence in the Chicago region: native

Etymology: Symphoricarpos comes from the Greek words symphoreo, meaning "born together," and karpos, meaning fruit (in reference to the clustered fruits). Occidentalis means "of or from the West."
