Are Celery and Celeriac the Same Thing? Unraveling Stalk vs. Root
Explore the unique differences, uses, and flavors of celery and celeriac for your kitchen and garden.
Are Celery and Celeriac the Same Thing?
Celery and celeriac, often confused due to their similar names and botanical relationship, are distinct vegetables with different characteristics, appearances, and culinary uses. Both belong to the Apium graveolens species, but each is cultivated and celebrated for unique features: celery for its crisp stalks, and celeriac for its flavorful root.
This guide explores their differences, flavors, nutritional value, growing tips, and the best ways to prepare and enjoy each vegetable in your kitchen.
Understanding Celery and Celeriac: Botanical Relations
Celery (Apium graveolens var. dulce) and celeriac (Apium graveolens var. rapaceum) are variants of the same plant species, but they have been bred for different culinary purposes.
- Celery: Cultivated mainly for its long, firm, crispy green stalks and flavorful leaves. The root of celery is thin and not palatable for eating.
- Celeriac (also known as celery root): Grown specifically for its large, bulbous, tuberous root with a distinctive taste, while its stalks and leaves are less vigorous and generally not eaten.
Key Differences: Appearance, Taste, and Texture
| Feature | Celery | Celeriac |
|---|---|---|
| Botanical Family | Apiaceae (carrots, parsley, parsnips) | Apiaceae (carrots, parsley, parsnips) |
| Main Edible Part | Stalks & leaves | Root (tuber) |
| Appearance | Long, upright, green stalks with leafy tops | Large, round, knobby, brown-skinned bulb (often called the “ugliest vegetable”) |
| Raw Texture | Crisp, crunchy | Firm, slightly chewy, crisp when shredded |
| Flavor | Mild, watery, grassy, slightly bitter | Earthy, nutty, stronger celery flavor, hints of parsley and sweetness |
| Common Culinary Uses | Raw as snacks, salads, dips; cooked in soups, stocks, casseroles | Mashed, roasted, puréed; grated raw in salads; cooked in soups, stews, briskets, gratins |
Visual Guide: How to Tell Them Apart
- Celery: Recognizable for its straight, ribbed, green stalks. Commonly found bundled in supermarkets.
- Celeriac: Looks like a rough, gnarled turnip or oversized root with tangled brown skin and small rootlets. When peeled, reveals pale ivory flesh.
Culinary Uses: How Are Celery and Celeriac Used?
Celery in the Kitchen
- Raw: Popular in salads, snacks (ants-on-a-log), and crudité platters. Used as a vehicle for dips and spreads.
- Cooked: A classic ingredient for flavor bases (mirepoix, soffritto). Adds subtle flavor and crunch to soups, stews, casseroles, and stocks.
- Appetizers: Stalks are stuffed (with cheeses or peanut butter) or used in appetizers.
Celeriac in the Kitchen
- Raw: Shredded or julienned in salads and slaws for its nutty and refreshing character.
- Cooked: Mashed, roasted, boiled, baked, pureed into soups or used in gratins. Pairs well with potatoes, carrots, or parsnips.
- Creative Dishes: Schnitzels, fritters, vegetable “noodles,” and savory pies like cottage or shepherd’s pie.
Epicurious describes its flavor as “celery meets parsley,” making it versatile for hearty and delicate dishes alike.
Nutritional Profiles: Celery vs. Celeriac
| Nutrient (per 1 cup, raw) | Celery | Celeriac |
|---|---|---|
| Calories | 16 | 65 |
| Carbohydrate (g) | 1 | 14 |
| Protein (g) | 0 | 2 |
| Fat (g) | 0 | 0 |
| Vitamin C | Low | High |

| Vitamin A | Higher | Lower |
| Folate | Higher | Lower |
| Phosphorus, Iron, B6 | Lower | Higher |
Celery is celebrated for its extremely low calorie and carbohydrate content, making it a favorite for light snacking and healthy meal plans. It is rich in vitamins, minerals, and phytonutrients with anti-inflammatory properties and retains most nutrients after steaming.
Celeriac is more calorie-dense and rich in vitamins C and K, and provides valuable amounts of potassium and phosphorus. As a root vegetable, it can help support bone, heart, and metabolic health, and may help reduce the risk of diabetes.
Both offer unique nutritional benefits and can be used to complement different dietary needs.
Growing Celery and Celeriac: Tips for Gardeners
- Climate: Both prefer cool, moist, fertile soils and are considered marshland plants.
- Soil: Deep, loamy, water-retaining soil is ideal. Avoid heavy clay and hardpans for celery.
- Planting: Start seeds indoors in late winter or early spring; transplant after danger of frost. Germination can be slow and variable; overhead lighting helps.
- Water/Nutrients: Consistent moisture is key. Planters with water reservoirs can help maintain ideal conditions.
- Celeriac Harvest: Ready 100-110 days from seeding or 80-90 days from transplant. Harvest when the tuber is large and knobby; peel away the rough exterior before use.
Growing: Key Differences
- Celery is grown for stalks and leaves, which require steady moisture and nutrient supply for crisp texture.
- Celeriac is grown for the root, with much less focus on stalk palatability. It thrives in similar conditions but is hardier for root harvesting.
Cultural requirements for both are largely similar, though celeriac may require soil mounding or covering before harvest to blanch and preserve quality.
Shopping and Preparation Tips
How to Select, Store, and Prep Celery
- Look For: Firm, crisp stalks with bright green color. Avoid limp or yellowing stalks.
- Storage: Keep in vegetable drawer, wrapped in plastic or stored in water for freshness. Lasts up to two weeks.
- Preparation: Wash thoroughly; trim ends and leaves. Use raw or cooked as desired.
How to Select, Store, and Prep Celeriac
- Look For: Large, heavy bulbs without soft spots or excessive root hairs.
- Storage: Store unpeeled bulbs in a cool, dark place; will keep for several weeks.
- Preparation: Trim top and bottom, and peel thick skin and rootlets. Use immediately, or submerge peeled slices/shreds in water with lemon to prevent browning (oxidation).
Celeriac oxidizes quickly, similar to apples or potatoes.
Substituting Celery and Celeriac in Recipes
- Though their flavors overlap, celery and celeriac are generally not interchangeable due to differences in texture and cooking properties.
- Celery offers crunch, wateriness, and a milder flavor that excels in raw preparations and soups.
- Celeriac brings earthiness, nutty sweetness, and a dense consistency that works in purees, mash, roasted dishes, and more.
- In certain recipes—like stews or roasted vegetable medleys—you can substitute one for the other in small quantities for a flavor boost, but expect textural differences.
Frequently Asked Questions (FAQs)
Q: Are celery and celeriac the same plant?
A: Yes, both derive from Apium graveolens but represent different cultivated varieties: celery for its stalks and celeriac for its root.
Q: Is celeriac the root of regular celery?
A: No, celeriac is not the root of the celery commonly found in stores. It is a separate variety specifically grown for its root; the stalks of celeriac are typically not palatable.
Q: Can I eat celeriac raw?
A: Yes, celeriac can be eaten raw when peeled and grated, adding crunch and fresh flavor to salads and slaws. Make sure to soak or dress quickly to prevent browning due to oxidation.

Q: Which is healthier: celery or celeriac?
A: Both are nutritious but offer different benefits. Celery is extremely low-calorie and good for hydration and anti-inflammatory effects. Celeriac is richer in vitamins C and K, potassium, and offers more energy per serving.
