Other names and notes
(Green-stemmed Joe-Pye Weed) Joe-Pye Weeds have leaves in whorls of 3 to 4 leaves on tall (from 3 to 7 feet) stout stems. Flowers are purple or pink, small, but numerous in branched clusters atop the stem. This variety has a solid stem, greenish with purple usually at the leaf nodes. The plant has a vanilla scent when bruised hence the common name. 4 to 7 pink to purplish flowers in each of the branched clusters which form a dome shape. Leaves are toothed, have a pinnate vein arrangement. This is a native plant that grows well in the home garden as a backdrop specimen. Single plants will grow into nice clumps in just a few years. The species name, purpureum, is from the Latin for "purple."

Notes: This plant was not listed on Martha Crone's 1951 inventory of plants in the Garden at that time and added in later years. It is native to a few counties in Minnesota in the NE section of the state and to counties in the SE quadrant including some metro countries but plant surveys did not include it in Hennepin, Scott or Anoka.
