  1. Rudbeckia

    Rudbeckia is a plant genus of 23 species in the family Asteraceae. The species are commonly called coneflowers and black-eyed-susans; all are native to North America and many species are cultivated in gardens for their showy yellow or gold flower heads. The species are herbaceous, mostly perennial plants growing to 0.5–3 m tall, with simple or branched stems. The leaves are spirally arranged, entire to deeply lobed, 5–25 cm long. The flowers are produced in daisy-like inflorescences, with yellow or orange florets arranged in a prominent, cone-shaped head; "cone-shaped" because the ray florets tend to point out and down as the flower head opens. A large number of species have been proposed within Rudbeckia, but most are now regarded as synonyms of the limited list given below. Several of these currently accepted species have several accepted varieties. Some of them, are popular garden flowers, distinguished for their long flowering times. There are many cultivars of these species. Rudbeckia species are used as food plants by the caterpillars of some Lepidoptera species including Cabbage Moth and Dot Moth.
