Black-eyed Susan is a cheerful, easy-to-grow wildflower that thrives in full sun to partial shade and tolerates a wide range of soil types. Water regularly during the first season to establish roots, after which it becomes quite resilient and low-maintenance. It self-seeds freely, attracts pollinators, and provides beautiful golden-yellow blooms from summer into fall.
