Rudbeckia hirta (Black-Eyed Susan) is a biennial or short-lived perennial boasting brilliant yellow daisylike flowers, 3 in. wide (7 cm) with a dark chocolate center disk. Enjoying a fairly extended blooming season, from early summer to fall, the flowers are attractive to butterflies, birds, and pollinating insects. They are borne atop stiff, upright stems clad with rough, hairy, lance-shaped leaves, 3-7 in. long (7-17 cm). This native prairie plant forms a rosette of leaves the first year, followed by flowers the second year. It will bloom the first year from seed planted in early spring. Black-Eyed Susan self-seeds freely and keeps a presence in the landscape. Putting on a spectacular show in the garden when other plants are starting to fade, Rudbeckia hirta tolerates heat, drought, and a wide range of soils except wet ones. The cheerful blossoms of the Black-eyed Susans are best in natural landscapes where they are allowed to self-sow and roam freely.
