Native to USA
The flowers of spurges are occasionally visited by small bees, Syrphid flies, and wasps. The seeds are consumed by the Mourning Dove, Greater Prairie Chicken, and to a lesser extent by the Bobwhite and Horned Lark. Because the milky latex in the stems and foliage is poisonous, this plant is rarely consumed by mammalian herbivores.

Sometimes this plant is referred to as Euphorbia dentata. Toothed Spurge is closely related to Euphorbia cyathophora (Wild Poinsettia), which also occurs in Illinois. This latter species has shiny leaves that turn red at the base near the inflorescence; it is the showier of the two plants.
