Achillea (its virtues said to have been discovered by Achilles). Compositae. Includes Ptarmica. About 100 species, some of which are hardy herbaceous border and alpine perennials of easy culture.
Leaves simple or compound, often ternate: fl.-heads small, corymbose or racemose; receptacle nearly flat or convex, chaffy; ray fls. pistillate, fertile, the rays white or pink; disk fls. perfect, fertile.
Most of the achilleas can be grown in ordinary garden soil, preferring open sunlight and well-drained situations. Some are alpine or sub-alpine and require rock-garden conditions. These are indicated under the individual species. Dwarf kinds make carpets in dry, sunny places; large kinds suitable for wild gardens.{{SCH}}
