Indian Summer Rudbeckia
A 1995 AAS winner which is compact, multi-branching, and a prolific producer of huge, colorful blooms. These are the largest, most astonishing Black-eyed Susans you'll ever see. Grow them as an annual, starting them indoors in April, transplanting when the soil is warm, and there will be 26"-30" plants with 5"-8" flowers from mid-August through the first few frosts. Golden yellow blossoms with chocolate-brown centers make for excellent cut flowers (with a long vase life) and are a beautiful sight in a garden.
