Kochia scoparia is found along roadsides and in disturbed areas in lower to middle elevations. It grows erect and branched. The stems turn red as the summer advances. It is generally considered an undesirable weed, although it was apparently first introduced as an ornamental. Kochia scoparia is an annual. The flowers occur in axillary clusters and develop into a fruit called a "utricle." Martin & Hutchins define a utricle as "a one-seeded fruit with a thin pericarp, the seed not attached to the wall." The utricles of Kochia scoparia have five small wings.
