Helianthus pauciflorus - Prairie Sunflower
Prairie Sunflower (Helianthus pauciflorus) is a herbaceous perennial and is either unbranched or sparingly branched. Its central stem is typically green or reddish brown with scattered, short white hairs that are rather stiff and give it a rough texture. The opposite leaves can get up to 6" long and 2" across, and are typically found on the lower part of the plant. Its yellow flowers occur individually at tops of the central stem and any upper lateral stems with 10-25 ray florets surrounding many reddish brown or yellow disk florets. The root system produces numerous rhizomes, which can aggressively form dense colonies quickly, and its roots release allelopathic chemicals that inhibit growth of other plants near it.
