Describe the plant here... {{Inc| Helianthus tracheliifolius, Mill. Resembles H. strumosus, but st. and fl.-stalks usually rough-hairy and lvs. thinner, green on both sides: branches and fl.-stalks rough- hairy. Aug., Sept. Dry soil, Pa. to Wis. Helianthus decapetalus, Linn. Wild Sunflower. St. 2-5 ft. high, branched above: lvs. 3-8 in. long, ovate- lanceolate, sharply serrate, thin, rough above, finely pubescent beneath: fls. 2-3 in. across, numerous; rays light yellow, generally more than 10, in spite of the specific name. July-Sept. Moist soils, Que. to Ga., west to Mich, and Ky. G.C. II. 16:601.—Under cult, it has given rise to the horticultural var. multiflorus, (H. multiflorus, Hort.). Fig. 1796. B.M. 227. G.C. III. 10:421. Gn. 27:66, pp. 71, 74; 45, p. 373. Gt. 43, p. 554. Gng. 3:83. F.R. 2:413. G. 21:592. G.W. 47:627.—The many garden forms of var. multiflorus differ mainly in the extent of doubling, season of blooming, habit of plant and size of fl. Among the best are: Var. flore-pleno (sometimes advertised as var. duplex)and var. grandiflorus, almost completely double (G. 4:427; 11:231); var. major, fls. larger than common (G. 4:163); var. maximus, very large, single fls. with pointed rays; var. simplex, an alleged single form; Soliel d'Or, with quilled florets, like a cactus dahlia. Multiflorus varieties are the most popular of perennial sunflowers, and deservedly so. If the double forms are grown on poor soil, or are allowed to remain for several years without being divided, they become single. }} ==Cultivation==  ===Propagation===  ===Pests and diseases===  ==Species==  ==Gallery== {{photo-sources}} <gallery> Image:Upload.png| photo 1 Image:Upload.png| photo 2 Image:Upload.png| photo 3 </gallery> ==References== *[[Standard Cyclopedia of Horticulture]], by L.
