description
Achillea millefolium is a flowering plant in the Asteraceae family.
Yarrow is an erect herbaceous perennial plant that has a spreading
rhizomatous growth form and it produces one to several stems that grow up to 1 meter (a little over 3 feet) in height.
Yarrow's leaves are covered in varying
degrees of hairiness (called pubescence) and are evenly distributed along its stem. These almost feathery leaves
are 5–20 cm long, bipinnate or
tripinnate; they are cauline and are arranged spirally on the stems with the largest leaves being near the
middle and bottom. The leaves are more or less clasping.
The plant's inflorescence has 4 to 9 phyllaries and contains ray and disk flowers.
Generally there are 3 to 8 ray flowers that are shaped ovate to round and colored white to pink. The number of disk
flowers range from 15 to 40. The inflorescence appears as a flat-topped
cluster. Yarrow's fruits are small achenes.
Yarrow has a strong scent that is sweet and reminiscent of chrysanthemum.
