Plant Description

Brown Eyed Susan is known for its branching habit and long bloom season that can extend into fall. It establishes quickly and fills gaps between slower-growing perennials. This species often behaves as a short-lived perennial but reseeds reliably. Cutting back in spring encourages strong new growth.
