Black yarrow

Achillea atrata | Also known as: Black milfoil, Achillea, Yarrow | Rating: 0 votes | Print / Pdf

A native of the Alps, Achillea atrata has delicate deep green fern-like foliage and flowers that look rather like daisies with lots of white petals and a yellow centre. They grow naturally in rocky grasslands, so they'll grow well in gritty soil or in a rockery. It was first described in 1753 by Carl Linnaeus. It likes plenty of sunshine and will cope with cold temperatures right down to -23C.
