European origin, but naturalized across Canada.
Yarrow (Achillea millefolium) is a widely distributed native plant with so much going for it. It is drought tolerant, the fresh and dried foliage has a pleasant fragrance, it is a popular nectar source for butterflies and is the host plant of many native moths and beetles. Yarrow spreads via rhizomes and will proliferate readily in the garden. Note, seeds are very small.
No pre-treatment required. Sow seed at soil surface. Do not let seedling dry out while establishing.
