Celery, that crisp, refreshing vegetable often found in salads, soups, and as a standalone snack, holds a unique place in the culinary world. But what exactly is celery? Is it a root, a stem, or something else entirely? Understanding its botanical classification and nutritional profile is key to appreciating its versatility and health benefits. Let’s delve into the world of celery and explore its fascinating characteristics.
Celery: A Botanical Overview
To understand what type of food celery is, we need to examine its botanical origins. Celery, scientifically known as Apium graveolens, belongs to the Apiaceae family, also known as the carrot or parsley family. This family is characterized by aromatic plants with hollow stems and compound leaves. Other familiar members of this family include carrots, parsley, dill, fennel, and parsnips.
Understanding the Celery Plant
The celery plant is a biennial, meaning it typically lives for two years. However, it is usually cultivated as an annual for its edible parts. The part we commonly eat as celery is actually the petiole of the plant. The petiole is the stalk that connects the leaf blade to the stem. So, technically, when we eat celery stalks, we are consuming the leaf stalks, not the stem itself.
The plant develops a rosette of leaves in its first year, supported by these fleshy petioles. In the second year, if allowed to grow, it produces a flowering stalk with small, white flowers that eventually develop into small fruits containing seeds. These seeds are also edible and have a distinct celery flavor.
Celery Varieties: A Spectrum of Options
Celery comes in various varieties, each with slightly different characteristics in terms of color, size, and flavor. The most common type found in supermarkets is Pascal celery, known for its green stalks and crisp texture. Other varieties include golden self-blanching celery, which has lighter-colored stalks, and celeriac, also known as celery root, which is grown primarily for its edible root. While all these varieties belong to the same species, Apium graveolens, they have been selectively bred for different traits.
Celery: A Nutritional Powerhouse
Beyond its botanical classification, celery is renowned for its impressive nutritional profile. It’s a low-calorie food packed with vitamins, minerals, and antioxidants, making it a valuable addition to a healthy diet.

Growing Your Own Celery
For those with a green thumb, growing your own celery can be a rewarding experience, providing fresh, homegrown produce right from your garden. While it can be a bit challenging, with proper care and attention, you can successfully cultivate celery at home.
Starting from Seed or Transplants
Celery can be started from seeds or transplants. Starting from seed requires more time and patience, as celery seeds can be slow to germinate. Transplants, which are young celery plants that have already been started indoors, offer a head start and can be easier for beginner gardeners.
Soil and Sunlight Requirements
Celery thrives in moist, well-drained soil that is rich in organic matter. It prefers a slightly acidic to neutral soil pH. It also needs plenty of sunlight, ideally at least six hours of direct sunlight per day.
Watering and Fertilizing
Consistent watering is crucial for celery growth, as it needs a constant supply of moisture. The soil should be kept consistently moist but not waterlogged. Regular fertilization with a balanced fertilizer can also help promote healthy growth.
Pest and Disease Control
Celery can be susceptible to various pests and diseases, such as aphids, celery leaf tiers, and fungal diseases. Regular monitoring and appropriate pest and disease control measures can help protect your celery plants.
Harvesting Your Celery
Celery is typically ready to harvest when the stalks are about 6-8 inches long. You can harvest the entire plant or individual stalks as needed. Simply cut the stalks at the base of the plant.
What exactly is celery, botanically speaking?
Celery (Apium graveolens) is classified botanically as a vegetable belonging to the Apiaceae family, also known as the carrot or parsley family. It is a biennial plant, though it is typically cultivated as an annual for culinary purposes. The edible parts we commonly consume are the stalks (petioles) and sometimes the leaves.
The celery plant consists of a fibrous stalk that grows from a short root. The stalks are tightly packed together, forming a bunch. While often perceived as a simple vegetable, understanding its place in the plant kingdom helps clarify its relation to other vegetables and herbs like carrots, parsley, and fennel.
Is celery a fruit or a vegetable, and why?
Celery is undoubtedly a vegetable. Botanically, a fruit develops from the flower of a plant and contains seeds. Vegetables, on the other hand, are other edible parts of the plant such as roots, stems, and leaves. Since celery stalks are the petioles or leaf stalks of the plant, it definitively falls under the category of vegetables.
In common culinary usage, the distinction between fruits and vegetables is sometimes blurred, often based on sweetness and how they’re used in dishes. However, adhering to the botanical definition, celery, with its stalk composition, is without question, a vegetable.
What are the main nutritional benefits of eating celery?
Celery is remarkably low in calories and rich in essential nutrients, making it a healthy addition to any diet. It’s a good source of vitamins A, C, and K, as well as folate and potassium. These vitamins play vital roles in vision, immune function, blood clotting, and maintaining electrolyte balance respectively.
Furthermore, celery contains beneficial plant compounds like antioxidants and phytonutrients, which may help protect against cellular damage and reduce inflammation. The high water content and fiber in celery also contribute to hydration and promote digestive health.
How can celery be used in cooking and culinary applications?
Celery’s versatility makes it a staple in kitchens worldwide. It can be enjoyed raw as a crunchy snack, dipped in hummus or peanut butter. It’s a key ingredient in salads, providing texture and a mild, savory flavor.
In cooked dishes, celery is often used as an aromatic base, providing depth of flavor to soups, stews, and sauces. It pairs well with other vegetables, meats, and poultry. Celery can also be juiced or blended into smoothies for a refreshing and nutritious beverage.
What are the different varieties of celery available?
While most grocery stores carry standard green celery, there are actually several varieties. Pascal celery is the most common type, known for its crisp, green stalks and mild flavor. Golden celery, also known as self-blanching celery, has paler stalks and a sweeter taste.
Celeriac, or celery root, is another variety grown for its edible root, which can be mashed, roasted, or used in soups. Leaf celery, also known as cutting celery, is grown for its flavorful leaves, which are often used as a herb.
Does celery have any potential allergens or side effects?
Celery is considered a common allergen, especially for individuals with birch pollen or mugwort pollen allergies, due to cross-reactivity. Allergic reactions can range from mild oral allergy syndrome (itching or tingling in the mouth) to severe anaphylaxis. It’s important for individuals with known celery allergies to carefully read food labels and avoid products containing celery.
Additionally, due to its high water content, consuming large amounts of celery may have a diuretic effect, increasing urine production. While generally harmless, this should be considered by individuals taking diuretic medications or those prone to dehydration.
How should celery be stored to maintain its freshness?
Proper storage is key to keeping celery crisp and fresh for longer. The best way to store celery is in the refrigerator. Wrap the whole bunch tightly in aluminum foil or place it in a sealed plastic bag. This helps to retain moisture and prevent it from drying out and becoming limp.
Another method is to trim the base of the celery stalk and stand it upright in a container with a little bit of water. Change the water every day or two. Celery stored properly can remain fresh for up to two weeks.
