Black-Eyed Susan

These popular North American perennials (plant genus Rudbeckia) bloom from July until frost. Black-eyed Susans' long blooming period, plus their rich colors and carefree nature, makes them particularly valuable in perennial gardens. Black-eyed Susans are also delightful when mass planted as landscape features. They need plenty of sun and good drainage, and will naturalize in meadows. A long-lasting cut flower, too.
