     Tall Boneset is a perennial plant that typically grows two to six feet tall and can spread about two to three feet wide. Its small, star-shaped flowers are about 1/8 inch across, dull white, and form large, flat-topped clusters up to eight inches wide. The leaves are lanceolate, opposite, ranging from two to six inches long and about an inch wide, occasionally toothed along the margins and covered with fine hairs. Tall Boneset thrives in dry upland prairies, open woods, thickets, clearings, and fields throughout eastern and central North America. It prefers dry to medium moisture, well-drained soils and can often be found in disturbed areas where it may form large colonies. (SF)
