RUDBECKIA

These big, warm-colored daisies are stalwarts of the summer and autumn garden. 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 encourages rebloom late in season. Divide perennials when they become crowded, usually every few years.
