Celery (Apium graveolens) is a cultivated plant, variety in the family Apiaceae, commonly used as a vegetable. Depending on location, either its stalks, or its hypocotyl, are eaten and used in cooking.In North America the dominant variety most commonly available in trade is celery, Apium graveolens var.elery is used around the world as a vegetable. In North America for the crisp petiole (leaf stalk). In Europe the hypocotyl is used as a root vegetable. The leaves are strongly flavoured and are used less often, either as a flavouring in soups and stews or as a dried herb.
Celery root, also known as celeriac (so elegant!) or celery knob (so crude!), is just what its name claims it to be: the root of the celery plant. This ugly brown hairball of a vegetable has a lovely mild, celery-like flavor with a starchy, rather potato-like texture. It's a surprising but winning combination.
