Shrub to 1 m tall Leaves: alternate, stalked, dark green and sometimes hairy above, paler and hairy beneath, 2 - 6 cm long, 1 - 2 cm wide, narrow oblong to elliptic with a wedge-shaped to rounded base and a blunt to slightly pointed tip, toothed, with three major veins radiating from base. Inflorescence: tightly branched (panicle), borne at the end of the current year's growth on a stalk rarely reaching 5 cm, 1 - 3 cm long, semi-circular to short egg-shaped. Flowers: with five white, clawed petals resembing tiny ladels and five stamens. Fruit: a dark brown, round, three-parted berry-like capsule about 3 - 5 mm wide, with three shiny reddish brown nutlets. Twigs: slender, green to brown and hairy when young, becoming brown to dark gray and smooth.

Similar species: Ceanothus americanus has mostly egg-shaped leaves, and the inflorescences are borne on long stems arising from the leaf axils.

Flowering: late May to early June

Habitat and ecology: Rare in the Chicago Region, found in low dunes and sandy soils near Lake Michigan.

Occurence in the Chicago region: native

Notes: Ceanothus herbaceus is sometimes grown as an ornamental and has a symbiotic relationship with a nitrogen-fixing bacteria. Insects are attracted by the flowers, deer eat the leaves, and birds eat the fruit. Native Americans once made the leaves into a tea and used the large woody roots as fuel on bison hunts and when firewood was scarce. Colonists used the leaves as a substitute for black tea after the Boston Tea Party to support patriotism during the American Revolution. A dye is made from the dark red roots.

Etymology: Ceanothus comes from an ancient Greek name for a different plant. Herbaceus means "not woody," referring to the small leafy branches of the new growth.
