*CVU, *GipP, *Glep, *HNF, *HSF, *Strz, *VVP. Also naturalised NT, SA, Qld, NSW, ACT, Tas. Native to Europe. An ornamental herb that occasionally persists in abandoned gardens and has weakly naturalised in some areas.

This species is often mistakenly identified as Achillea millefolium, from which it differs in its winged rachises that are often toothed or lobed between the primary pinnae. The two species are, however variable in this feature, and some collections are difficult to identify with confidence.
