HARDY AGERATUM

Eupatorium Celestinum

Hardy Ageratum, Eupatorium Celestinum is commonly called Hardy Ageratum, Wild Ageratum and Blue Mistflower.  Its vibrant blue blossoms, sticky and aromatic, were once a staple in Native American healing practices. Inhalation of the plant’s smoke during ceremonies was common, and its flowers and roots brewed into teas to treat ailments ranging from stomachaches to fevers.

As a garden plant, blue mistflower is a fine choice for perennial borders, wetland restoration sites, and moist meadows, where it has room to spread.  It makes a wonderful medium-height ground cover.  It is a good ground cover for a wildlife garden or a moist meadow. Plants are also used as butterfly nectar plants, cut flowers, accents or as part of a grouping or mass planting. This wildflower has showy blooms and provides erosion control.
