"Spotted joe-pyeweed thrives in marshes, rich fens and swamps. It also does well in man-made moist expanses such as ditches, seepage areas and wet fields. Above all else the plant flourishes in the non-shaded environments that are also abundant in wetlands.
It is a larval host to the Clymene moth, the eupatorium borer moth, the ruby tiger moth, and the three-lined flower moth. The plant also attracts butterflies and honeybees." -- Wikipedia
