Vernonia noveboracensis
Vernonia noveboracensis, the New York ironweed or vein-leaf hawkweed, is a plant in the family Asteraceae. It is native to the eastern United States, from Florida to Massachusetts and west to Tennessee, Alabama, and West Virginia and to southern Ontario.
Vernonia noveboracensis blooms in August and grows in wetlands and moist soils. It is classified as FAC+ (wetland indicator status). Its active growth period is during the summer. The lowest temperature at which it can survive is −33 °F (−36 °C). Vernonia noveboracensis competes through its early season growth and tall stem height. A hard stem also allows the plant to withstand windy conditions. V. noveboracensis is not known to be an invasive species, nor is it toxic. This plant attracts butterflies, birds, and other insects, but it is resistant to deer.
Dihydromikanolide is a sesquiterpene lactone found in V. noveboracensis, which is used to treat infections. Native Americans use its leaves to make a tea (tisane) that relieves labor pain and is used as a blood tonic. The roots of the plants were also made into teas that relieved stomach ulcers and tooth pain.
