ACHILLEA

This genus of 100-odd species of clumping or mat-forming perennial plants is a member of the large Asteraceae (daisy) family. Achillea species grow throughout Europe and northern and western Asia in a range of habitats including alpine. Some species can be invasive. The foliage is usually finely divided with a fern-like appearance and is often aromatic. The daisy-like flowerheads are flattened or rounded, comprising numerous small flowers in white, pale cream, lemon, and pink. A number of cultivars are available in brighter shades, and these make excellent border plants. The genus is named after Achilles, the hero of Greek mythology, who is said to have known of the plant's wound-healing qualities.

CULTIVATION

Most species are easily grown in well-drained soil in full sun. They can tolerate quite poor conditions and are fairly frost hardy. Alpine and dwarf species require perfect drainage and protection from winter rain if downy-leaved. Propagation is by division or seed.

Top Tip

Achillea are hardy plants that will multiply rapidly. After the flowers have died down in winter, prune the clumps back to stimulate strong regrowth in spring.
