Russian Knapweed grows in a bush one to three feet high with stiff branches and forms dense colonies with creeping roots. Flowers are ½ to ¾ inch across and thistle-like, ranging from white to pink to lavender in color. Bracts are smooth with rounded tips, green and cobwebby. It is toxic to horses and considered a highly invasive, noxious weed by the State of New Mexico and many other states. A single Russian knapweed plant can produce about 1,200 seeds per year. The findings of a recent study suggest it is a promising source of natural antioxidant, antimicrobial, anti-cholinesterase and anti-amylase agents for the management of oxidative damage, and pharmaceutical, food, and cosmeceutical purposes. In folk medicine, the plant has been used for many years as an emetic, anti-epileptic and anti-malaria remedy. Source.
