Celery
Summary
Celery (Apium graveolens) is a marshland plant in the family Apiaceae that has been cultivated as a vegetable since antiquity. Celery has a long fibrous stalk tapering into leaves. Depending on location and cultivar, either its stalks, leaves or hypocotyl are eaten and used in cooking. Celery seed powder is used as a spice.
Celery leaves are pinnate to bipinnate with rhombic leaflets long and broad. The flowers are creamy-white, in diameter, and are produced in dense compound umbels. The seeds are broad ovoid to globose, long and wide. Modern cultivars have been selected for either solid petioles, leaf stalks, or a large hypocotyl. A celery stalk readily separates into "strings" which are bundles of angular collenchyma cells exterior to the vascular bundles.
Wild celery, Apium graveolens var. graveolens, grows to tall.
Celery is a biennial plant that occurs around the globe. It produces flowers and seeds only during its second year. The first cultivation is thought to have happened in the Mediterranean region, where the natural habitats were salty and wet, or marshy soils near the coast where celery grew in agropyro-rumicion-plant communities.
North of the Alps, wild celery is found only in the foothill zone on soils with some salt content. It prefers moist or wet, nutrient rich, muddy soils. It cannot be found in Austria and is increasingly rare in Germany.
First attested and printed in English as "sellery" by John Evelyn in 1664, the modern English word "celery" derives from the French céleri, in turn from Italian seleri, the plural of selero, which comes from Late Latin selinon, the latinisation of the selinon, "celery". The earliest attested form of the word is the Mycenaean Greek se-ri-no, written in Linear B syllabic script.
Celery was described by Carl Linnaeus in Volume One of his Species Plantarum in 1753.
The plants are raised from seed, sown either in a hot bed or in the open garden according to the season of the year, and, after one or two thinnings and transplantings, they are, on attaining a height of , planted out in deep trenches for convenience of blanching, which is effected by earthing up to exclude light from the stems.
