Joe Pye Weed - A native to the prairie state, this large perennial grows 6-8 feet high and wide. Blooming in late summer with broad, plate like flowers that resemble sedums, in a dusty purple. A dwarf form is available. Make sure you buy a named variety, like “Gateway” in order to get large flowers and a stronger plant. Prefers sun, moist soil, and looks best if cut down to the ground in early spring.
