Everybody loves them as wildflowers, but the beautiful Black-Eyed Susan was never a dependable garden flower until these incredible perennial hybrids were created. Most famous is Rudbeckia "Goldsturm," the one you see everywhere every summer, blooming like crazy for weeks and weeks--probably the most popular perennial in the world. They all return dependably with more and more blooms each year. Best of all, the Rudbeckias are among the easiest plants to grow, so they're must-haves for any flower garden.
