RUDBECKIA (Rudbeck’ia) This group of hardy, herbaceous perennials and annuals come from North America and belong to the Daisy family, Compositae. They form neat clusters, 1 to 3 feet high. The oval to elliptic shaped leaves are mostly basal and grow 3 to 6 inches long. The single or double flowers are 2 to 6 inches across and are colored yellow and sometimes brightly bicolored reddish-brown. Pulling off the dead flowers will increase the blooms. Rudbeckias are commonly known as the Black- or Brown-eyed Susan, Gloriosa Daisies and Coneflowers. These plants produce lovely cut flowers.
