Are Onions Vegetables or Herbs?
Onions are vegetables.
They are the edible part of the plant, specifically the bulbs, and do not contain seeds.
Onions are categorized as bulbous plants that store their nutrients underground and are therefore referred to as root vegetables.
They are part of the allium species and can be grown from the seeds of an onion plant, but the onions themselves do not contain seeds within them.
Other types of onions, such as scallions and shallots, are also considered vegetables.
Therefore, onions are definitely vegetables and not herbs.
Quick Tips and Facts:
1. Onions are classified as vegetables, rather than herbs. While they do share some similarities with herbs, such as their pungent flavor and use in culinary applications, onions are classified as vegetables due to their bulb-like structure and high nutritive value.

Onion Classification: Vegetable Or Herb?
The classification of onions has long sparked debate over whether they are vegetables or herbs. To resolve this, we need to examine the nature of onions and their botanical characteristics. Culinary-wise, onions are predominantly regarded as vegetables. They are the edible bulbs of the plant, frequently utilized in savory recipes to enhance taste and scent. However, botanically speaking, onions are classified as bulbs, categorizing them as part of the bulbous plant family.

These plants are characterized by their unique flavors and the presence of sulfur-containing compounds that give them their pungent taste and aroma. Each member of the allium species has its own distinct characteristics, but they all share similarities in terms of growth habit and culinary usage.

Onion Reproduction: Seeds Or Bulbs?
While many plants reproduce through the dispersal of seeds, onions have a unique method of reproduction. Onions do not contain seeds themselves, but instead reproduce through their bulbs. The bulbs of onions store nutrients and serve as an underground energy source for the plant. When an onion plant matures, it produces flowers that can develop into seeds, but these seeds are not present within the bulb itself. To grow new onion plants, the bulbs are separated and planted.
- Onions reproduce through their bulbs, not seeds.
- The bulbs store nutrients and serve as an energy source.
