Introduction to Arugula
Arugula (Eruca vesicaria sativa), also known as rocket, garden rocket, or roquette, is an annual herb that belongs to the Brassicaceae family—the same plant family as mustard, broccoli, and cauliflower. However, despite its rise as a popular salad green, arugula is not technically a lettuce. Its origins lie in the Mediterranean, where it has been cultivated for centuries as both a culinary ingredient and an herb for medicinal use.
- Leaf characteristics: Smooth to lobed, typically 2″–6″ tall; color ranges from bright to dark green, depending on age and variety.
- Flowers: White petals with purple veins, forming loose clusters.
- Other names: Rocket, roquette, rucola, salad rocket.

Culinary Uses of Arugula
The unique flavor and texture of arugula make it a favorite among chefs and home cooks. Its versatility means it can be enjoyed raw or cooked, used as a main ingredient or a garnish, and incorporated into a variety of cuisines.

- Salads: Arugula is often mixed with other greens to add pizzazz to salads. Its peppery punch balances well with citrus dressings and sweet fruits.
- Sandwiches & Wraps: Adds texture and flavor to sandwiches and wraps.
- Garnish: Fresh leaves are commonly sprinkled over pizzas, soups, or egg dishes as a final touch.
Cooked Uses

Arugula: Flavor and Taste
Arugula is renowned for its peppery, spicy, and slightly nutty flavor. Its taste has been variously described as “mustardy,” “tart,” or even “horseradish-like,” depending on the variety and maturity of the leaves. Younger baby leaves are milder, while mature leaves pack more of a punch.
| Type | Taste Notes | Best Uses |
|---|---|---|
| Baby Arugula | Delicate, less peppery, mildly nutty | Salads, sandwiches, pizzas |
| Mature Arugula | Robust, spicy, sharp | Pasta, pesto, sautés |
| Wild Arugula | Intense, pungent, complex (notes of pepper, horseradish, pine) | Use sparingly as garnish or in savory pies |
Growing and Selecting Arugula
Arugula requires a relatively short growing season—typically 35 to 50 days from planting to maturity. It thrives in cool climates and can be harvested multiple times per season when mowed or picked carefully. In home gardens, arugula is easy to grow and is relatively pest-resistant due to its pungent oils, though it bolts (quickly flowers and seeds) in hot conditions.
- Harvest: Choose fresh, crisp leaves. Younger leaves are sweeter and less bitter.
- Storage: Store arugula in the refrigerator, wrapped in a damp paper towel for up to five days.
- Seasonality: Most available in spring and fall, with some varieties grown year-round.
Types and Varieties of Arugula
Several species and cultivars of arugula are available for human consumption, each offering different flavor intensity and leaf shapes:
- Garden Rocket (Eruca vesicaria sativa): Commonly cultivated, milder flavor, rounded leaves.
- Wild Arugula (Diplotaxis tenuifolia): Intense, pungent flavor, narrow and deeply lobed leaves; often used sparingly in gourmet dishes.
- Sylvetta: A popular wild form in specialty markets, smaller and more robust.
