Black Eyed Susans are one of the most popular perennials available today, having earned the prestigious Perennial Plant of the Year Award in 1999.
Plants have a long season of bloom and a sturdy, upright habit. The gold daisy-like flowers have a distinct dark brown central cone and are held on branching stems. Do not deadhead these cones if you want winter interest since the black seed heads remain attractive throughout the winter and the seeds provide a source of food for small birds.
A classic garden combination includes upright Sedum 'Autumn Joy' and Perovskia atriplicifolia. It is an excellent perennial for providing color in late summer and is especially showy in mass plantings.
