Yarrow

Yarrow

Yarrow Achillea has dense clusters of flowering heads that are white in most species but may be pink or yellow. Most yarrows have divided leaves and those of a commonly seen species in North America Achillea millefolium are so deeply-divided that they look like little fern fronds. The petal-like ray-florets are female flowers and the disk-florets have both male and female flower parts. [CH] {MV}
