Eupatorium perfoliatum (Boneset)
Eupatorium perfoliatum, or Boneset, is a native wildflower and member of the Aster family. I first discovered Boneset growing at my pond and fell in love with this statuesque native, and its fragrant, showy white (sometimes pink) flower clusters. What I really found interesting was the way the bases of the leaves surround the stem and merge together (perfoliate). Boneset grows from two to four feet (and taller) in full sun to part sun and in - this is important - wet to consistently moist soil. That's why you will often find it near water, such as creek banks and ponds, but it is not an aquatic plant. Native Americans used it for making a tea to treat dengue (or breakbone fever), and it is still used medicinally. The bees, insects, and butterflies make a "beeline" to it all day long, and that's the truth. Zones 4-8.
