Eupatorium altissimum
Also called Tall Boneset, Upland Boneset
Eupatorium altissimum, with the common names tall thoroughwort and tall boneset, is a perennial herbaceous plant in the Asteraceae family with a native range including much of the eastern and central United States and Canada. It is a tall plant found in open woods, prairies, fields, and waste areas, with white flowers that bloom in the late summer and fall.
E. altissimum is native to eastern and central North America, from Ontario in the north, Nebraska in the west, Texas and the Florida Panhandle in the south, and Massachusetts in the east. It almost always grows on limestone soils in prairies, open woods, fields, and neglected areas.
