Helenium autumnale. Linn. (H. grandiflorum, Nutt.). Sneezeweed. Fig. 1792. St. 2-6 ft. leafy: lvs. mostly toothed, smooth: heads 1-1 ½ in. across, numerous, borne at the end of short, very leafy stalks; rays drooping, 3-cleft, lemon- yellow to bright yellow ; disk yellow. July-Oct. Moist places, Canada to Fla. and west to S. D., Kans. and Ala. B.M. 2994. Gn. 29:190; 55:218. A.G. 12:682. G.C. III. 10:433; III. 32:405.—Very showy. It has distinct merit for the back of borders, but is more appreciated in Eu. than in Amer. There are several garden forms: var. pumilum is 1-2 ft. high, a very free bloomer, and is largely grown for cut-fls. in some places. J.H. III. 59:109. Var. grandiflorum and var. superbum, (H. superbum, Hort.), are unusually vigorous and large-fld.; var. stria turn, has a maroon and gold disk, with vellow rays variously striped and splashed with rich crimson. J.H. III. 31:293. This should be distinguished from the striped forms of H. nudiflorum. Var. grandicephalum atropurpureum has almost entirely crimson n.-heads. Var. rubrum has deep red fls. A form known in the trade as H. grandicephalum compactum bicolor is also advertised. It seems to belong here.
