Tanacetum is a genus of about 70 species of flowering plant in the family Asteraceae, native to temperate regions of the Northern Hemisphere.[citation needed]

Common names include Tansy (Tanacetum vulgare; sometimes called Common Tansy or Garden Tansy) and Feverfew (Tanacetum parthenium); several other species are also known as tansies. Other common names include Bachelor's Buttons, Bitter Buttons, Boerenwormkruid, Buttons, Ginger Plant, Gold-buttons, Ponso, Solucanotu, Tanaceto, Tansy, Yomogi-Giku.[citation needed]

The name tansy is also sometimes given, improperly, (e.g. in the western United States) to ragwort, because in those areas ragwort is known as "tansy ragwort".[citation needed]


Standard Cyclopedia of Horticulture

Pyrethrum (a name used from the time of Dioscorides, the derivation from the Greek, much fire, referring to the acrid roots). Compositae. This name is still commonly used in garden literature and language although the genus has long been reduced to a section of Chrysanthemum. Almost every nursery catalogue offers P. roseum and its numerous varieties, which is referred by botanists to Chrysanthemum coccineum; also P. parthenifolium var. aureum, the golden feather, and P. uliginosum. (See Vol. II, p. 753.) All three of these are rather common in gardens and they are known to most lovers of hardy perennials. More recent introductions under the name Pyrethrum are P. Tchihatchewii, also spelled Tchihatcheffii, the "turfing daisy" (see Chrysanthemum Tchihatchewii, Vol. II, p. 756), and P. leucopiloides, Hausskn., a sub-alpine perennial with silvery white leaves and large yellow flower-heads. Asia Minor. Suitable for the rockery. This last species is not mentioned under Chrysanthemum.
