Celery seeds

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 is also used as a spice and its extracts have been used in herbal medicine. Celery leaves are pinnate to bipinnate with rhombic leaflets 3–6 cm (1.2–2.4 in) long and 2–4 cm (0.79–1.57 in) broad. The flowers are creamy-white, 2–3 mm (0.079–0.118 in) in diameter, and are produced in dense compound umbels. The seeds are broad ovoid to globose, 1.5–2 mm (0.059–0.079 in) long and wide. Modern cultivars have been selected for solid petioles, leaf stalks. 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 1 m (3.3 ft) tall.It occurs around the globe. 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 in English in 1664, the 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 Ancient Greek: σέλινον, romanized: 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.
