Helianthus maximiliani flowers

Flowering - July - October.

Habitat - Limestone glades, bluffs, bald knobs, rocky prairies, loess hills, roadsides, waste ground.

Origin - Native to U.S.

Other info. - This showy species can be found scattered nearly throughout Missouri but is actually only native to the western Ozark region and in the loess hills of the extreme northwest corner of the state. It has been introduced elsewhere. This is perhaps the easiest species of Helianthus to identify in Missouri. The alternate leaves, which are folded and falcate, and grayish cast of the entire plant are good characters to look for. This big plant does very well in cultivation but can get weedy if left undisturbed. Cultivated varieties are even more showy than the wild plants.

Photographs taken off Hwy 60, Carter County, MO., 8-31-03.

    Perennials , 50—300 cm (rhi-zomatous). Stems erect, 5—30 dm, scabrous to scabro-hispidulous. Leaves cauline; mostly alternate; petioles 0—2 cm; blades (light green to gray-green, 1-nerved, conduplicate) lanceolate, 10—30 × 2—5.5 cm, bases cuneate, margins usually entire, sometimes serrulate, abaxial faces scabrous to scabro-hispid, gland-dotted.

    Flowering late summer—fall. Prairies , fields, waste areas; 0—300(—2100+) m; Alta., B.C., Man., Ont., Que., Sask.; Ala., Ark., Calif., Colo., Conn., Del., D.C., Idaho, Ill., Ind., Iowa, Kans., Ky., Maine, Md., Mass., Mich., Minn., Miss., Mo., Nebr., N.J., N.Y., N.C., N.Dak., Ohio, Okla., Pa., S.C., S.Dak., Tenn., Tex., Utah, Va., Wash., W.Va., Wis., Wyo.; Mexico.

    Helianthus maximiliani is introduced in eastern Ontario and in Quebec. It appears to be native to midcontinental prairie regions and has spread along railroads and highways into all areas of North America. Its wide dispersal may be aided by cultivation for its attractive, showy floral displays. In addition to the usually conduplicate, single-nerved leaves and spikelike arrangement of the heads, it is distinguished by the whitish-canescent indument of the leaves and stems and the long-attenuate phyllaries.
