Rudbeckia also called Coneflower because they have a prominent brown or green cone. They start off with the cone; the little star shaped petals gradually stretch to form large dome headed flowers. Rudbeckia are mostly yellow and perfect for cut flowers.
Try planting these Perennial Plants with Verbena Bonariensis, Asters and Heleniums. Rudbeckia are also perfect for prairie style planting and look good with Grasses like Stipa Gigantea, Miscanthus, Molina and Pennisetum.
