Have you seen this plant in Minnesota, or have any other comments about it?
achillia multifolia is labeled as "native" on your Minnesota Wildflowers site, but as alien in Roger Tory Peterson's Field Guide to Wildflowers, and on the USDA website. Is this an "oops" or do you have other information on this plant?
Nancy, thanks for this particular question, as I have asked it myself.
According to Flora of North America ("FNA" is our definitive guide, see efloras.org) this species is native, though morphologically variable. FNA goes on to explain that some early botanists considered the variations separate species, others considered them variations of a single species. It seems now this is a Northern Hemisphere species that has hybridized sufficiently between North American and introduced plants to become a single, variable species.
FNA calls it native, as does the MN DNR big list-o-plants.

It grows all over in Litchfield. A great medicinal herb! God for bruises, burns, radiation, takes pain away from varicose veins, sunburn, but it is renowned for its ability to stop the blood from gushing wounds. Hence it's name "Achillea millefolium", named after the Greek leader of warriors in the Trojan War, who bound the wounds of his warriors with yarrow to staunch the flow of their blood.
