Rush Skeletonweed

Species
Chondrilla juncea

Rush skeletonweed (Chondrilla juncea) is a perennial and considered noxious under the BC Weed Control Act. Found on rangelands, roadsides, and disturbed habitats at mid-elevations in the dry grassland zone, infestations occur in the Vernon area, Crescent Valley, Kimberley, Windermere, and Creston. It is a major concern in the Kootenay and Okanagan regions.

Rush skeletonweed is a mass of wiry, milky fluid-filled stems and small yellow flowers, growing to 1.3 metres in height at maturity. Wiry stems are covered with stiff, reddish-brown hairs at the base. Barely visible narrow leaves give it a “skeleton-like” appearance.

Plants can produce 20,000 parachute-like seeds that travel easily with wind, water, animals, and humans along dry grasslands. Horizontal roots also aid reproduction. Rush skeletonweed reduces livestock and wildlife forage, and stems can cause serious problems with harvest machinery.
