What is Celery Stalk?
Celery (Apium graveolens) is a biennial plant in the Apiaceae family, prized for its fibrous, pale green stalks. Celery stalks are the long, fibrous petioles that connect the leaves to the base of the plant, typically harvested in bunches. These stalks are distinct from the leaves, roots, and seeds of the plant, each of which are also used in culinary or herbal contexts. In supermarkets, the term “celery” refers most often to the stalks, sold as tight clusters or bunches, which can be eaten raw, cooked, or juiced.
Celery Stalk Anatomy
- Petioles: The edible, elongated, crunchy sections referred to as stalks.
- Leaves: The leafy ends, used mainly as garnish or in stock.
- Root/Base: The bulbous root, sometimes used in soups.
Origin and Cultivation
Celery originated in the Mediterranean region and has been cultivated for thousands of years. Today, it thrives in temperate climates and is available year-round.
Seasonality: Spring, summer, fall, and winter celery crop cycles ensure consistent availability.
