Joe Pye Weed or Eutrochium maculatum

Eutrochium

From Wikipedia, the free encyclopedia


Eutrochium is a North American genus of herbaceous flowering plants in the sunflower family. They are commonly referred to as Joe-Pye weeds. They are native to the United States and Canada, and have non-dissected foliage and pigmented flowers.

Scientific classification:
Kingdom:     Plantae
(unranked): Angiosperms
(unranked): Eudicots
(unranked): Asterids
Order:          Asterales
Family:         Asteraceae
Genus:         Eutrochium
Species:       E. maculatum
Binomial name: Eutrochium maculatum

The genus includes all the purple-flowering North American species of the genus Eupatorium as traditionally defined. Eupatorium has recently undergone some revision and has been broken up into smaller genera. Eutrochium is the senior synonym of Eupatoriadelphus. Eupatorium in the revised sense (about 42 species of white-flowered plants from the temperate Northern hemisphere) is apparently a close relative of Eutrochium. Another difference between Eutrochium and Eupatorium is that the former has mostly whorled leaves and the latter mostly opposite ones. Eupatorium and Eutrochium are both placed in the subtribe Eupatoriinae, but South American plants which have sometimes been placed in that subtribe, such as Stomatanthes, seem to belong elsewhere in the tribe Eupatorieae.

Medicinal:

Joe Pye (Jopi in the Native tongue), an Indian healer from New England, used E. purpureum to treat a variety of ailments, which led to the name Joe-Pye weed for these plants.[10] Folklore says that Joe Pye used this plant to cure fevers. Folklore also states that American colonists used this plant to treat typhus outbreaks. The author Hemmerly writes that the Indians used Joe Pye Weed in the treatment of kidney stones and other urinary tract ailments.

Eutrochium maculatum

Eutrochium maculatum (spotted joe-pyeweed) is a North American species of flowering plants in the sunflower family. It is widespread through much of the United States and Canada. It is the only species of the genus found west of the Great Plains.

Eutrochium maculatum is an herbaceous perennial sometimes growing 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. The binomial name maculatum, meaning spotted, refers to the purple spots on the stem.

Spotted Joe-Pye weed 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 so abundant in wetlands.

Varieties:
Eutrochium maculatum var. bruneri (A. Gray) E. E. Lamont – western Canada (British Columbia to Saskatchewan), western USA (Minnesota west to Idaho, south to Arizona + New Mexico)
