About Prairie Sunflower

Prairie Sunflower is a hardy and adaptable annual that brings the classic beauty of sunflowers to even the most challenging, sandy sites. Reaching 1 to 6 feet in height, this branched plant features rough foliage and cheerful yellow flowers with dark centers that bloom from June through September. Native to the western and central United States and naturalized elsewhere, it is a pioneer species that thrives in disturbed areas, dry prairies, and sandy soils. It is fantastic for supporting local biodiversity, attracting a wide range of bees and butterflies, while its seeds provide a reliable food source for birds. As an annual, it completes its life cycle in one season but will readily re-seed. Unlike many perennial sunflowers, its seeds do not require pre-treatment (Germination Code A) and can be sown directly into sunny, well-drained spots.
