china
the onion plant has a fan of hollow, bluish-green leaves and its bulb at the base of the plant begins to swell when a certain day-length is reached. the bulbs are composed of shortened, compressed, underground stems surrounded by fleshy modified scale (leaves) that envelop a central bud at the tip of the stem. in the autumn (or in spring, in the case of overwintering onions), the foliage dies down and the outer layers of the bulb become dry and brittle. the crop is harvested and dried and the onions are ready for use or storage. the crop is prone to attack by a number of pests and diseases, particularly the onion fly, the onion eelworm, and various fungi cause rotting. some varieties of "a. cepa", such as shallots and potato onions, produce multiple bulbs.

the onion plant has been grown and selectively bred in cultivation for at least 7,000 years. it is a biennial plant, but is usually grown as an annual. modern varieties typically grow to a height of . the leaves are yellowish- to bluish green and grow alternately in a flattened, fan-shaped swathe. they are fleshy, hollow, and cylindrical, with one flattened side. they are at their broadest about a quarter of the way up, beyond which they taper towards a blunt tip. the base of each leaf is a flattened, usually white sheath that grows out of a basal disc. from the underside of the disc, a bundle of fibrous roots extends for a short way into the soil. as the onion matures, food reserves begin to accumulate in the leaf bases and the bulb of the onion swells.
