Celery is a vegetable of which the stalks (or petioles) are edible.
Celery is found on market stalls from June to February.
Nutritional value of celery
For a long time celery has been used as a medicinal plant (aphrodisiac). It is low in calories (15 kilocalories per 100 grammes) and rich in mineral salts (potassium, calcium and iron), trace elements and fibre.
Celery is a species that has been cultivated; thus the petiole has been developed (as opposed to celeriac, of which the root has been developed).
Celery heads are rather heavy. Its foliage is blond to dark green. Its stalks are white, fleshy, shiny and crunchy when fresh.
