ACHILLEA Alpine Yarrow

Most of the varieties of Achillea grow several feet tall and are found in the middle or at the back of the herbaceous border. There is, however, a popular dwarf variety which belongs in the rockery – A. tomentosa. There are several other Alpine Yarrows and all are useful for covering areas of dry sandy soil or crevices between rocks. Flowers are borne on short stems in summer and the plants are easily propagated by division. Sprinkle Slug Pellets around the leaves in spring.

VARIETIES: The basic details of A. tomentosa are height 6 in., spread 1 ft.

Flowering period: July-September. The finely-divided greyish leaves form a prostrate mat and the tiny yellow flowers are borne in flat heads which are about 3 in. across. A. ‘King Edward’ (A. lewisii) also bears yellow flowers, but it blooms earlier and is a bushier and smaller plant. A. clavennae bears white flowers in loose clusters.

SITE AND SOIL: Reguires well-drained infertile soil in full sun.

PROPAGATION: Divide clumps in spring.
