flowers are produced in mid summer, with large sepals, and a five-lobed white corolla.
It grows in open wooded areas, ditches, and hillsides; in
gardens it can be invasive, growing from spreading roots.
Uses
Indian hemp was used as a source of fiber by
Native Americans, to make hunting nets, fishing lines, clothing, and twine. It was also used in
herbal medicine to treat syphilis, rheumatism, intestinal worms, fever, asthma, and dysentery. Although the toxins from the plant can cause nausea and catharsis, it has also been used for slowing the pulse.
