Tanacetum coccineum

Chrysanthemum coccineum, Willd. (Pyrethrum roseum, Bieb., not Web. & Mohr. P. hybridum, Hort.). Fig. 933. Glabrous perennial, 1-2 ft. high: st. usually unbranched, rarely branched at the top: lvs. thin, dark green, or in dried specimens dark brown: involucral scales with a brown margin; rays white or red in such shades as pink, carmine, rose, lilac, and crimson, and sometimes tipped yellow, but never wholly yellow. Caucasus, Persia. F.S. 9:917. Gn. 26, pp. 440, 443. Gng. 2:7; 5:309. R.H. 1897, p. 521. Not B.M. 1080, which is C coronopifolium. The first picture of a full double form is R. H. 1864:71.—This species is the most important and variable of all the hardy herbaceous kinds. There have been perhaps 700 named horticultural varieties. There is an anemone-fld. form with a high disk. The species is also cult. in Calif. and France for insect powder. C. atrosanguineum, Hort., is said to be a good horticultural variety with dark crimson fls. The C. roseum of Weber & Mohr being a tenable name, Hoffmann proposes Ascherson's name, C. Marschallii, for the P. roseum of Bieberstein; but Willdenow's C. coccineum is here retained. ^CH
