Prairie Sun black-eyed Susan (Rudbeckia hirta 'Prairie Sun') features large, green-eyed, daisy-shaped flowers in orange, transitioning to yellow towards the tips. Derived from native midwestern parents, this short-lived perennial is well-adapted to the Chicago climate and will reseed (if not deadheaded) to produce future generations in your garden. Hummingbirds and songbirds enjoy the nectar/seeds.
