Daucus carota, whose common names include wild carrot, European wild carrot, bird's nest, bishop's lace, and Queen Anne's lace (North America), is a flowering plant in the family Apiaceae. It is native to temperate regions of the Old World and was naturalized in the New World.
Domesticated carrots are cultivars of a subspecies, Daucus carota subsp. sativus.
The wild carrot is a herbaceous, somewhat variable biennial plant that grows between 30 and 120 cm (1 and 4 ft) tall, and is roughly hairy, with a stiff, solid stem. The leaves are tripinnate, finely divided and lacy, and overall triangular in shape. The leaves are 5–15 cm (2–6 in) long, bristly and alternate in a pinnate pattern that separates into thin segments. The flowers are small and dull white, clustered in flat, dense umbels. The umbels are terminal and about 8–15 cm (3–6 in) wide. They may be pink in bud and may have a reddish or purple flower (the "ruby") in the centre of the umbel. The lower bracts are three-forked or pinnate, which distinguishes the plant from other white-flowered umbellifers. As the seeds develop, the umbel curls up at the edges, becomes more congested, and develops a concave surface. The fruits are small, dry, bumpy, oval and flattened, with short styles and hooked spines, as well as protective hairs surrounding it. The fruit has two mericarps, or bicarpellate. The endosperm of the fruit grows before the embryo. The dried umbels detach from the plant, becoming tumbleweeds. The function of the tiny red flower, coloured by anthocyanin, is to attract insects. The flowers bloom from May to September.
