Common Sunflower
Kansas’s familiar sunflower is a branching wild annual, not simply a smaller version of the single-headed crop plant.
Artwork inspired by William Dickerson
Wild common sunflowers carry numerous flower heads on coarse, hairy stems. Their seeds feed birds and small mammals, while the long bloom season supports bees, beetles, and butterflies across disturbed ground and prairie margins.
Photograph responsibly from a roadside pullout or public path; wild populations also preserve genetic diversity important to the globally cultivated sunflower crop. Let observation replace interference: do not feed, bait, flush, pick, peel, or reposition Common Sunflower.
