Botanical Name

ACHILLEA clavennae

Plant Common Name

Silvery Yarrow

General Description

Silvery yarrow is a low-growing, semi-evergreen perennial native to the mountainous regions of Eastern Europe. It forms a dense mat of finely dissected, gray-green leaves which are aromatic and covered with soft hairs. Many flat-topped clusters of small, white flowers appear from midsummer to early autumn. They are attractive to butterflies, and contrast nicely with the silvery foliage.

This drought-tolerant plant grows best in full sun and thrives in a range of soils, but must have good drainage. It is suitable for rock gardens or the edges of waterwise mixed borders.
