The originated in western United States, but has since expanded east. The prairie sunflower is considered a be a weed.

Helianthus petiolaris originated in the dry prairies of Minnesota, Oregon, Texas, the Dakotas, California, and other states in western and central United States. It has since expanded its distribution to throughout the eastern United States and into central and western Canada. Helianthus petiolaris is now the most widely distributed species of sunflower besides H. annuus.
The prairie sunflower is commonly found growing in sandy areas. They can also be found in heavy clay soil and in dry prairies. The prairie sunflower is unable to grow in shady areas; it needs to be in direct sunlight. It requires dry to moist soil. This species of sunflower is an annual flower, blooming between the months of June and September. The prairie sunflower can be found from the Great Plains, the Rockies, the desert regions of the Southwest, etc.
Individuals of this species occur as shrubs and also as taprooted annuals. They can grow up to four feet tall (120cm).

The stem of the flower is erect and hairy. The leaves on the shrub are alternate, has a lanceolate shape, rough in texture, are bluish-green in color, and has a length between 2-5inches.
Helianthus petiolaris has flower heads reminiscent of those of a common sunflower, Helianthus annuus. The fruits of the flowers are known as achenes. The flower head contains 10-30 yellow ray florets, surrounding 50-100 dark red-brown disc florets, and green, lanceolate phyllaries (bracts). The center of the flower has hints of white due to the presence of white hairs on the chaff. The flowers attract butterflies and bees for pollination.
The seeds in the plant are edible and can be ground up into an oily meal or into a butter.
Powdered leaves of the prairie sunflower are said to work well with the healing of sores and swellings.
