Achillea is a genus of about 85 flowering plants, in the family Asteraceae, commonly referred to as yarrow. They occur in Europe and temperate areas of Asia. A few grow in North America. These plants typically have frilly, hairy, aromatic leaves.

These plants show large, flat clusters of small flowers at the top of the stem. These flowers can be white, yellow, orange, pink or red. A number of species are popular garden plants.


Read about Achillea in the Standard Cyclopedia of Horticulture 

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.CH
