Joe Pye Weed
Eutrochium purpureum
Family Asteraceae
Joe Pye weed runs the busiest airport in the late-summer garden — its dusty-mauve flower domes, held five to seven feet up, land monarchs and swallowtails by the dozen as they fuel for migration. Few natives put on a wildlife show this effortless to watch.
Born for moist ground, it anchors a rain garden or a damp back border with real architecture, then feeds birds from its seed heads all winter. Dwarf forms fit smaller beds at three to four feet. Give the back fence a native skyline.
