The inflorescent is a panicle of racemes with whorls of flowers ½–1½' long. Individual flowers are 1/8 inch long, have no petals and are yellowish-green three-winged sepals that turn brown at maturity. They are wind-pollinated.
Each flower becomes a dry capsule with one seed. Seeds are dark brown and 3-angled, tapering at their tips.
