Morphology
Low growing, multi-stemmed woody shrub to 1 m. Leaves 3-veined, toothed, mostly oblong or elliptic, the larger ones less than 2 cm wide. Flowers in several to many hemispheric to short-ovoid panicles, terminating leafy shoots of the season; petals 5, white.
Notes

Also called Prairie Redroot. The specific epithet probably refers to the fact that the flowers occur on new wood, because the plant is not herbaceous. Endangered in several states. Of the 55 species of Ceanothus in North America, only two occur in the Northeast.
