Subspecies

From Weakley’s Flora of the Southeastern United States: South Carolina (2020): “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) 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 (Ramsey, pers. comm.; Ramsey 2011; Levin 2011). Later work suggests that A. borealis should be narrowly applied to a western North American entity, and that the oldest name available for native eastern North American Achillea is A. gracilis, a course followed here.”
