Eutrochium maculatum ( İngilizce )

wikipedia EN tarafından sağlandı

Eutrochium maculatum, the spotted joe-pyeweed,[2] is a North American species of flowering plant in the family Asteraceae. It is widespread through much of the United States and Canada.[3] It is the only species of the genus Eutrochium found west of the Great Plains.[4]

This herbaceous perennial sometimes grows as high as 2 m (6 ft 7 in). Stems are sometimes completely purple, sometimes green with purple spots. One plant can produce numerous rose-purple flower heads in late summer, each head with 8-22 disc flowers but no ray flowers.[5] The specific name maculatum, meaning spotted, refers to the purple spots on the stem.[6][4]

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.[7][8]

It is a larval host to the Clymene moth, the eupatorium borer moth, the ruby tiger moth, and the three-lined flower moth.[9] The plant also attracts butterflies and honeybees.[10][11]
