Sweet Black-Eyed Susan is a long-lived perennial. This deep-rooted Rudbeckia grows at the base to form large clumps with strong multiple stems that may also branch at the top, resulting in an impressive floral display. The plant has a pleasant, sweet smell when blooming and many pollinators frequent the flowers. Rudbeckia subtomentosa prefers a medium clay soil, in full sun and will also bloom in partial shade. Plants can be divided and moved in early spring.
