Plant Sale Text: Blue mistflower or wild ageratum, formerly in the Eupatorium genus, attracts many butterflies, long-tongued bees and skippers! It is found growing in woodland edges and roadsides throughout Central and eastern US. It spreads by rhizomes and is perfect for naturalizing large spaces. To control its spread, try planting it in drier soils. Blue mistflower occasionally blooms until November, providing color late into fall.
