Celery, Apium graveolens, is an aromatic biennial plant in the family Apicaceae grown primarily for its stalk and taproot which are used as vegetables.
The rhombic leaves of the celery plant grow in a rosette and are 3–6 cm (1.2–2.4 in) long and 2–4 cm (0.8–1.6 in) broad on a branched central stem which is highly ribbed. The plant produces creamy white flowers in dense umbels (an umbrella of short flower stalks) and produces broad oval seeds 1.5–2 mm (<0.1 in) long and wide. Celery is a biennial plant that is commonly grown as an annual and it can reach a height of about 1 m.
Celery is eaten around the world as a vegetable. Both the taproot and leaves are often used. Temperate countries grow celery for its seeds, which are often mixed with salt to make celery salt for seasoning
