Western Sunflower (Helianthus occidentalis)
The Western Sunflower is much more than an accent plant—it’s a keystone in Wisconsin’s dry, open habitats such as prairies, meadows, and rocky open woods, where it enjoys full sun and well-drained soils. Blooming in late summer, it offers vital nectar and pollen to native bees, butterflies, and beetles when few other wildflowers remain. Its seeds nourish birds like goldfinches, while its rhizomatous roots help stabilize soil in rocky, sunlit habitats. By supporting pollinators, enriching the food web, and anchoring biodiversity, this naive perennial plays a steady, sustaining role in prairie restoration and native plant communities
It typically grows to a height of two to four feet. Its bright yellow flowers are daisy-like and measure about 1-1/2 to 2-1/2 inches across. The vibrant yellow disk in the center of the flower is composed of numerous, tiny disk florets. These flowers are surrounded by several overlapping bracts, which are light green, linear-lanceolate in shape, and about 1/4 inch long. The plant features long, often reddish, stiff stems that are mostly bare except for a few pairs of small, widely spaced leaves. The majority of the leaves form a basal rosette at the base of the plant, with the basal leaves being large, rough, and hairy, and attached by long stalks. The stem leaves are smaller and lanceolate, measuring around one to three inches long and 1/4 to 3/4 inches wide. (SF)
