Twenty Mile Germplasm boreal yarrow (pdf file)
Achillea millefolium var. borealis, Selected Class “Natural”
Twenty Mile boreal yarrow is a 2006 Selected Class Germplasm release derived from parent material collected near Portage, Alaska, in 1994 (Wright, 2006). This is a coastal collection and does well in coastal settings, but has sufficient adaptability to be useful in inland areas also. Yarrow, like the parsley family species, has the ability to create the appearance of a natural meadow stand in reseeded areas; the presence of the white/cream flowers breaks up the usual homogeneity of grass plantings.
