The showy garden rudbeckias that brighten summer and fall borders are descended from wild plants native mainly to the eastern U.S. All are tough and easy to grow. Blossoms have yellow or orange rays and a raised central cone. They make good cut flowers; cutting also encourages rebloom late in season.
