Facts

Velvetleaf Indian-mallow is native to China where it is cultivated for its fibers, used to make string, rope, shoes, rugs and other products. It is also used in Chinese herbal medicine to treat fever, dysentery, and stomach ache. In North America, it is an introduced invader and a serious pest of agriculture and disturbed areas.
