Achillea millefolium, also known as Common Yarrow or Ajidamoowaanow (squirrel tail) / Waabigooniinzens (flower which is little) (Ojibwemowin), is a perennial wildflower native to the UP. It is hardy, prefers poor soil, and spreads by rhizome. Blooming from May to early August, it has a disk of white flowers enjoyed by a variety of pollinators. The feathery foliage is sought by birds for nest material. Yarrow is also a host plant for many types of caterpillars and other beneficial insects, and has been used medicinally by humans.
 
Depending on conditions, yarrow can grow from 1-3' in height, but it tolerates being mowed and can be incorporated into lawns, creating textural diversity. It prefers medium to dry sandy loam and full sun, and will reward you with richly textured arched leaves and sturdy stems. It is resistant to drought, foot traffic, and deer.
