'''''Rudbeckia''''' ({{pron-en|rʌdˈbɛkiə}})<ref>''Sunset Western Garden Book,'' 1995:606–607</ref> is one of at least four [[genus|genera]] within the [[flowering plant]] family [[Asteraceae]] whose members are commonly known as [[coneflower]]s; the others are ''[[Echinacea]]'', ''[[Dracopis]]'' and ''Ratibida''.
They are [[herbaceous]], mostly [[perennial plant]]s (some [[annual plant|annual]] or [[biennial plant|biennial]]) growing to 0.5-3 m tall, with simple or branched stems. The [[leaf|leaves]] are spirally arranged, entire to deeply lobed, 5-25 cm long. The [[flower]]s are produced in [[daisy]]-like [[inflorescence]]s, with yellow or orange florets arranged in a prominent, cone-shaped head; "cone-shaped" because the ray florets tend to point out and down (are decumbent) as the flower head opens.
A large number of [[species]] have been proposed within ''Rudbeckia'', but most are now regarded as [[synonym (biology)|synonym]]s of the limited list given below. Several of these currently accepted species have several accepted varieties. Some of them (for example the [[Black-eyed Susan]], ''R. hirta''), are popular garden flowers, distinguished for their long flowering times. There are many [[cultivar]]s of these species.
''Rudbeckia'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including [[Cabbage Moth]] and [[Dot Moth]].
The name was given by Carolus Linneaus in honor of his teacher at Uppsala University, Professor [[Olof Rudbeck the Younger]] (1660-1740), and his father, Professor [[Olof Rudbeck the Elder]] (1630-1702), both of whom were botanists.
