Celery (Apium graveolens var. dulce) is a plant variety in the family Apiaceae, commonly used as a vegetable. The plant grows to 1 m (3.3 ft) tall. The leaves are pinnate to bipinnate with rhombic leaflets 3–6 cm long and 2–4 cm broad. The flowers are creamy-white, 2–3 mm in diameter, and are produced in dense compound umbels. The seeds are broad ovoid to globose, 1.5–2 mm long and wide. 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.
