This genus rarely is considered a "good" one. Most species are now usually treated as Tanacetum, formerly but erroneusly it was included in Chrysanthemum sensu lato. Russian taxonomists have treated Pyrethrum as a separate genus. 56 species in the "Flora of the USSR", the bulk of them in the Caucasus and in Central Asia; only 8 are of wide distribution. Some species are already known in cultivation in the FSU and in Europe. Among them are P. carneum Bieb., P. coccineum (Willd.) Worosch., P. corymbosum (L.) Scop. and P. parthenium (L.) Smith, all known under Tanacetum. Some other species have been tested by botanical gardens and deserve special attention.
