Rush skeletonweed is a perennial forb that can grow up to 4 ft. (1.2 m) tall. Coarse-looking, multiple stems appear leafless due to inconspicuous leaves and arise from a basal rosette of sharply lobed leaves. The lower 4-6 in. (10.2-15.2 cm) of stem is covered with coarse brown hairs. Both stem and leaves produce a milky sap when broken. Flowers are small and yellow and develop in the mid-summer to fall. Mature, healthy plants can produce 1,500 flower heads and up to 20,000 seeds. Rush skeletonweed invades dry rangelands in the Western United States, displaces native species, and reduces forage for livestock and wildlife. Rush skeletonweed is native to regions of Europe, Asia, and Africa and was accidentally brought to the United States as a contaminant of fodder in 1914.
