Through Flowering plant, Leaf and Native species
The species is widely naturalised outside of its natural range and is used as a vegetable; modern cultivars have been selected for their leaf stalks (celery), a large bulb-like hypocotyl (celeriac), and their leaves (leaf celery).
Description
Apium graveolens is a stout biennial or monocarpic perennial herb, producing flowers and seeds only once, during its second or a later year. It grows up to 1 m (3 ft) tall, with all parts of the plant having a strong celery odour. The stems are solid with conspicuous grooves on the surface (sulcate). The leaves are bright green to yellowish-green, 1- to 2-pinnate with leaflets that are variously shaped, often rhomboid, up to 6 cm (2+1⁄2 in) long and 4 cm (1+1⁄2 in) broad.
The flowers are produced in umbels, mostly with short peduncles, with four to twelve rays. The individual flowers are creamy-white to greenish-white, 2–3 mm (3⁄32–1⁄8 in) across. The fruit is a schizocarp, broadly ovoid to globose, 1–1.5 mm (3⁄64–1⁄16 in) long and wide.

Taxonomy
The species Apium graveolens was first described by Carl Linnaeus in 1753. A large number of varieties have been described, none of which are accepted by Plants of the World Online as of May 2024. It has been selected as the type species of the genus Apium, and through that, of the family Apiaceae and the order Apiales.
The cultivar groups have often been given botanical variety names, but more accurately cultivar group names under the International Code of Nomenclature for Cultivated Plants. Thus cultivated celery was often called Apium graveolens var. dulce, but as cultivated plants, Apium graveolens Dulce Group.
Other vernacular names have been used, including "smallage", which is mostly archaic but still in occasional use, primarily outside of the species' native range.
Distribution and habitat
Wild celery is native to much of Eurasia, ranging from Ireland in the west, through Europe north to Scotland, Denmark and Poland, and east to the Caucasus and Central Asia, and as far as the western Himalayas, and also through Macaronesia and North Africa to West Asia and the Arabian Peninsula. It is widely naturalised outside this range, including in Scandinavia, North and South America, Africa, India, central, eastern and southern Asia, and New Zealand. The cultivar groups may also be naturalised.
It is a plant of damp places, usually near the coast where the soil is salty, typically on the brackish reaches of tidal rivers, ditch and dyke margins, saltmarshes, and sea walls. North of the Alps, wild celery is found only in the foothill zone on soils with some salt content.
Uses
Wild celery was used for its medical properties and as a condiment by the Ancient Egyptians, Greeks and Romans, and also in China. The species was later developed as a vegetable, particularly in Italy from the 16th century. Modern cultivars have been selected for different uses, falling into three groups according to the part that is mainly eaten:
- Celery (Apium graveolens Dulce Group; syn. Apium graveolens var. dulce), is used for its leaf stalks, which may be eaten raw or cooked.
- Celeriac (Apium graveolens Rapaceum Group; syn. Apium graveolens var. rapaceum), is used for its swollen bulb-like hypocotyl.
- Leaf celery, smallage or parcel (Apium graveolens Secalinum Group; syn. Apium graveolens var. secalinum), has larger leaves; both the leaves and stems are eaten.
