Family

Asteraceae

Botanical Name

ACHILLEA x lewisii 'King Edward'

Plant Common Name

Dwarf Wooly Yarrow, King Edward Yarrow

General Description

Silvery-leaved, low-growing and drought tolerant, this is the perfect small yarrow for rock gardens and sunny border edges. A cross between the species Achillea clavennae and Achillea tomentosa, 'King Edward' forms a mat of narrow, gray-green, minutely toothed leaves. Loose, flattened clusters of buttery, pale primrose flowers bloom on short stems from late spring to midsummer. These are attractive to butterflies and have a soft, pretty appearance. Regular deadheading may extend flowering.

This diminutive yarrow grows and flowers best in full sun and must have sharply drained soil for success. It is a sweet, very hardy perennial that looks great in rock gardens or at the edges of well-drained borders.
