Celery (Apium graveolens var. dulce) is a plant variety in the family Apiaceae, commonly used as a vegetable. In North America, commercial production of celery is dominated by the varieties called Pascal celery. Gardeners can grow a range of cultivars, many of which differ little from the wild species, mainly in having stouter leaf stems.
Celery is used around the world as a vegetable for the crisp petiole (leaf stalk). The leaves are strongly flavoured and are used less often, either as a flavouring in soups and stews or as a dried herb. Celery, onions, and bell peppers are the "holy trinity" of Louisiana Creole and Cajun cuisine. Celery, onions, and carrots make up the French mirepoix, often used as a base for sauces and soups. Celery is a staple in many soups, such as chicken noodle soup.
