Flowering - July - November.

Habitat - Cultivated.

Origin - Native to U.S.

Other info. - The plant pictured above is one of the many cultivated varieties of H. annuus . These varieties range in size from shorter than a meter to over 2.5 meters. Many of the cultivated plants do not grow true from seed and will eventually revert back to the wild type plants over a few generations. To view the wild type plant click here .
The largest of these cultivated H. annuus get massive taproots that exceed 2.5m in length. The taller plants often need to be staked as the large flower heads weigh too much for the stem to support.
Cultivated sunflowers are the plants from which birdseed, sunflower oil, and our edible sunflower seeds arise. These cultivated plants do not readily escape in Missouri.
The lower-most leaves of the stem on this species are opposite but quickly become alternate for the rest of the stem length. Seedling plants have opposite leaves.

Photographs taken at the Peck Ranch Wildlife Refuge, Carter County, MO., 7-12-03.

3. Helianthus annuus Linnaeus, Sp. Pl. 2: 904. 1753.

Common sunflower

Helianthus annuus subsp. jaegeri (Heiser) Heiser; H. annuus subsp. lenticularis (Douglas ex Lindley) Cockerell; H. annuus var. lenticularis (Douglas ex Lindley) Steyermark; H. annuus var. macrocarpus (de Candolle) Cockerell; H. annuus subsp. texanus Heiser; H. aridus Rydberg; H. jaegeri Heiser; H. lenticularis Douglas ex Lindley; H. macrocarpus de Candolle

Annuals, 100—300 cm. Stems erect, usually hispid. Leaves mostly cauline; mostly alternate; petioles 2—20 cm; blades lance-ovate to ovate, 10—40 × 5—40 cm, bases cuneate to subcordate or cordate, margins serrate, abaxial faces usually ± hispid, sometimes gland-dotted . Heads 1—9. Peduncles 2—20 cm. Involucres hemispheric or broader, 15—40(—200+) mm diam. Phyllaries 20—30(—100+), ovate to lance-ovate, 13—25 × (3—)5—8 mm, (margins usually ciliate) apices abruptly narrowed, long-acuminate, abaxial faces usually hirsute to hispid, rarely glabrate or glabrous, usually gland-dotted. Paleae 9—11 mm, 3-toothed (middle teeth long-acuminate, glabrous or hispid). Ray florets (13—)17—30(—100+); laminae 25—50 mm. Disc florets 150+(—1000+); corollas 5—8 mm (throats ± bulbous at bases), lobes usually reddish, sometimes yellow ; anthers brownish to black, appendages yellow or dark (style branches yellow) . Cypselae (3—)4—5(—15) mm, glabrate ; pappi of 2 lanceolate scales 2—3.5 mm plus 0—4 obtuse scales 0.5—1 mm. 2 n = 34.

Flowering summer—fall. Open areas; 0—3000 m; St. Pierre and Miquelon; Alta., B.C., Man., N.B., N.W.T., N.S., Ont ., P.E.I., Que., Sask.; Ala., Ariz., Ark., Calif., Colo., Conn., Del., D.C., Fla., Ga., Idaho, Ill., Ind., Iowa, Kans., Ky., La., Maine, Md., Mass., Mich., Minn., Miss., Mo., Mont., Nebr., Nev., N.H., N.J., N.Mex., N.Y., N.C., N.Dak., Ohio, Okla., Oreg., Pa., R.I., S.C., S.Dak., Tenn., Tex., Utah, Vt., Va., Wash., W.Va., Wis., Wyo.; Mexico; intoduced nearly worldwide.

Helianthus annuus is widely distributed, including weedy, cultivated, and escaped plants. It is the only native North American species to become a major agronomic crop. Despite its considerable variability, attempts have failed to produce a widely adopted infraspecific system of classification. Forms with red-colored ray laminae, known from cultivation and occasionally seen escaped, trace their ancestry to a single original mutant plant. It hybridizes with many of the other annual species.
