Celery (Apium graveolens) is a species belonging to the Apiaceae family,
with a cosmopolitan distribution. Celery has a long, fibrous stem that
tapers into leaves. Depending on the location and cultivar, its stems,
leaves or hypocotyl are eaten and used in cooking. Celery seed powder is
used as a spice. A biennial, glabrous herb with a strong,
characteristic odour, featuring an axonomorphic root and stems up to 100
cm tall, erect, deeply grooved and solid. Lower leaves once pinnately
dissected, with 3–7 segments 1–5 cm long, coarsely toothed or sometimes
almost pinnatifid, with a delta- or rhomboid-shaped outline; petioles
slender, sheathing for most of their length; upper leaves mostly deeply
trilobed or trisected, with petioles sheathing for almost their entire
length. Depending on the part of the plant that is used, they are
classified into three main commercial varieties: Apium graveolens
var. dulce: This is the most common; its fleshy, crisp and juicy
petioles or stems (stalks) are eaten. Apium graveolens var. rapaceum:
This is grown for its globular, thickened root, which is very popular in
the cuisines of central and northern Europe. Apium graveolens var.
secalinum: Similar to parsley, it is mainly used as an aromatic herb due
to the intensity of its leaves.
