ACHILLEA. Yarrow. Europe, Asia, N. America. Rugged perennial daisies, with finely cut, often aromatic leaves and flat-topped flower clusters. The robust, often garish hybrids are most familiar to gardeners. However, the species are also pretty and often more graceful. They are easily grown in full sun, with well drained soil and moderate to occasional watering when established. The following are hardy to 10oF. and below.
millefolium 'Pink Island Form' (formerly classified as A. borealis). A pink variant of a normally white flowered species, received from the Santa Barbara Botanic Garden. It forms broad mats of dark green leaves, with clusters of rich pink blossoms rising continually on 2' stems, late spring to fall. We are also growing a race of short-stemmed, white flowered plants from the high Sierra.
