Achillea nobilis

Achillea nobilis, the noble yarrow, is a flowering plant in the sunflower family. It is native to Eurasia, widespread across most of Europe (except Scandinavia and the British Isles)[1] and also present in Turkey, the Caucasus, and Central Asia. It is reportedly present in Xinjiang Province in western China, but this is based on a single herbarium specimen collected in the 19th century.[2] The species is widely cultivated and has become naturalized outside of its range in North America and other parts of the world.[3][4]

Achillea nobilis has creamy-whitish or yellow flowers, and resembles common yarrow (Achillea millefolium) except with more flower heads that are smaller. The leaves of Achillea millefolium are much more finely dissected into needle-like segments.

The medium green foliage forms a low-growing clump in early spring and in late spring produces flowering stems that grow up to 30 inches tall; the stems end in flat flower clusters (umbels). The foliage and stems are covered with soft hairs.[5]
