Black-eyed Susan is a tough, cheerful wildflower that thrives in sunny to partly shaded garden beds with minimal attention. Water regularly during the first growing season to establish roots, then reduce frequency as the plant becomes drought-adaptable. Deadhead spent blooms to encourage continued flowering through summer and fall.
