Small, inconspicuous green flowers bloom along flowering stalks up to 3 ft tall. Dark-green leaves grow from the plant base to less than 1 ft tall. Plants filled in the study area in their third year of growth, and bloomed throughout June. This species was one of the least attractive to natural enemies in the early season, with less than half as many natural enemies as in the grass control.
