Rudbeckia maxima

A super-sized Black-Eyed Susan, Rudbeckia maxima is noted for its sturdy upright stems that have a strong architectural presence in the garden with bluish waxy leaves. Each coneflower features large yellow daisy-like flowers with a central dark brown cone throughout the early summer. Leave the flower stalks after they bloom so goldfinches can enjoy the seeds.
