Are Herbs Considered Vegetables? Breaking Down the Plant Categories

When it comes to plants used for food, the categories of fruits, vegetables, and herbs can be confusing. Herbs have leaves used for flavoring, while vegetables are edible plant parts. But are herbs considered a type of vegetable, or are they their own distinct group? Let’s break down the terminology and explain the relationship between these beneficial plants.

Herbs Defined

Culinary herbs are plants valued specifically for their flavorful, aromatic leaves. Common examples include basil, oregano, thyme, rosemary, parsley, cilantro, dill, mint, sage, and many more Herbs contain essential oils and phytochemicals that give them their potent scent and taste.

In cooking, herbs are used in relatively small quantities to add zest and aroma to foods, either fresh or dried. They are rarely served as a main part of a meal. Herbs can be perennial, annual, or biennial plants.

In addition to culinary use, some herbs are valued for medicinal properties. Herbal supplements and remedies utilize the roots, flowers, seeds, stems and leaves of certain herb species believed to have health benefits

How Vegetables Are Defined

The term vegetable is broader and encompasses any edible part of a plant. This includes:

• Roots – carrot, turnip, beet, radish

• Bulbs – onion, garlic, leek

• Stems – celery, asparagus

• Leaves – lettuce, spinach, cabbage

• Flowers – broccoli, cauliflower, artichoke

• Seeds – peas, beans, corn

• Fruits – tomato, cucumber, squash, pepper

Vegetables are usually eaten as part of a main dish or side for their nutrients. Some vegetable plants do produce edible leaves, like lettuce or spinach, but the entire leafy portion is consumed.

The Relationship Between Herbs and Vegetables

Herbs fit under the larger vegetable category because they are edible plant parts, specifically leaves, just utilized differently. So it’s accurate to say:

• All culinary herbs are vegetables, but not all vegetables are herbs.

• Herbs represent just one portion of the broader vegetable group – the leafy parts.

Think of the vegetable family as a tree. Vegetables are the trunk while herbs are a branch growing from that trunk.

Leafy herbs also have these distinctions:

• Most culinary herbs come from small, low-growing herbaceous plants rather than large vegetable plants.

• Herb leaves tend to be more pungent and aromatic than typical vegetable greens.

• Herbs are used in small amounts to add punchy flavor, while vegetable leaves constitute a main part of a dish.

Examples of Herb vs. Vegetable Leaves

To further illustrate the herb-vegetable relationship, let’s compare some common edible leaves:

Basil – Herb

Basil is the quintessential herb. The leaves of basil plants contain essential oils that lend a distinct flavor and aroma. Used fresh or dried, basil provides a punch of flavor critical in dishes like pesto, soups, pasta, and Italian cooking. A little basil goes a long way to add taste.

Lettuce – Vegetable

Lettuce is primarily grown as a vegetable crop for salads and sandwiches. Several cultivars are available, but all parts of the lettuce plant are edible, including the leaves, stem and sometimes roots. It is served as a main part of various dishes. The leaves are not intensely aromatic like basil.

Parsley – Herb

Parsley is another herb grown specifically for its fresh, grassy flavor. The leaves contain essential oils that enhance the taste and smell of many foods. Just a sprinkling of parsley leaves on top of a dish provides plenty of flavor.

Spinach – Vegetable

Spinach is a fast-growing leafy green vegetable that makes up a main portion of salads, soups, side dishes and other meals. The entire leaf is eaten and provides nutrients. But the leaves are not notably aromatic or extremely flavorful like an herb.

Thyme – Herb

Thyme is a classic culinary herb prized for its potent lemon-pine flavor notes. A little bit of fresh or dried thyme goes a long way in seasoning soups, stews, meats and other dishes. The essential oils in thyme give it its robust taste and smell.

Arugula – Either an Herb or Vegetable

Arugula is an example of a leafy green that straddles the line between herb and vegetable. In small amounts, arugula adds a peppery punch similar to an herb. But arugula is also served in larger quantities as a salad green or cooked green vegetable. So arugula can serve both purposes!

Herbs Offer Unique Benefits

Culinary herbs add immense flavor, variety and nutrition to everyday meals. Their diversity and versatility in global cuisines are invaluable.

Herbs also contain higher levels of antioxidants compared to most vegetables and fruits. Adding more fresh herb leaves to food is an easy way to boost your antioxidant intake for better health.

So while herbs and veggies may seem to overlap, understanding their subtle differences helps when cooking with plants or growing an edible garden. Both are vital pieces of healthy diets and lifestyles when used properly!
