Notes:

This widespread species was formerly considered to be identical to the European Achillea millefolium. It is now thought to be a native species. From Weakley's Flora 2015: "The Achillea millefolium aggregate is a taxonomically very complex
entity, with races of different ploidies, and both introduced and native genotypes in e. North America. Ramsey, Robertson & Husband (2008) have recommended treating native North American races as A. borealis; most eastern North American populations represent native North American races, most closely allied to e. Asian taxa, with only a few collections of European races from near old port cities."

Is attractive to bees, butterflies, and birds. Host for Painted Lady Butterfly. Deer-resistant. Can become aggressive and spread.
