Is Lime a Fruit or a Vegetable?
A lime is both a fruit and vegetable. Science classifies lime as a fruit, while the culinary usage classifies lime as a vegetable.
Lime is botanically named the Citrus aurantiifolia. Its popular plant name is the Key Lime Tree. Other lime species include:
- Citrus glauca (Desert lime)
- Citrus latifolia (Persian lime)
- Citrus hystrix (Makrut lime)
Limes find the perfect habitat in Central America and Mexico. Some sources believe limes originated in Northern India, Malaysia, and Myanmar.
Why Is Lime a Fruit?
Lime gets its classification as a fruit because it develops from flowers on the branches of the lime tree and contains seeds. Science defines fruit as plant parts that contain female reproductive organs.
All citrus trees can reproduce sexually. The male pollen from citrus blooms will fertilize a lime flower’s female ovary to produce a seed.
Once the bloom has been fertilized, it will fall from the tree, permitting the flower ovary to expand into a lime fruit.
Why Is Lime a Vegetable?
Limes have a very sour, almost bitter taste. For this reason, they are used more frequently in savory cuisine, hence their consideration as a vegetable.
The word vegetable is not considered to be a scientific classification. The term vegetable is used predominantly as a culinary label for more savory dishes.
In the broader sense, vegetable refers to the edible leaves, stems, roots, blooms, and even fruit of a plant. So, limes, although citrus fruits, would also be considered vegetables.
Lime vs. Lemon: What’s the Difference?
Limes and lemons are two different fruits that are related, but genetically different. Limes, like lemons and oranges, contain citric acid in their juice. For this reason, these fruits are considered citrus fruits.
Nutritionally, they resemble each other. When comparing them, their carbs, fat, and protein content are nearly identical. Limes will have a bit more carbs and calories, but the difference is insignificant.

Some experts believe that the lemon is the hybrid result of the breeding of a lime with a citron. The citron is a much larger yellow citrus fruit with an exceptionally thick outer skin. This is one of several theories.
Limes are cultivated in tropical and subtropical areas. Lemons can be successfully grown in moderate climates.
Both fruits are appreciated and used for their sour flavor. They can be found in numerous culinary dishes globally. Their uses are not limited to cooking but include flavoring, and food preservation.
Both lemons and limes are also used in cleaning products due to their antibacterial properties and fragrance.
But while they share many similarities, they also have noteworthy differences. The most obvious is in their appearance. Lemons are usually a vivid yellow while limes are a light green color. Some lime varieties may turn yellow with maturation.
Limes also tend to be smaller than lemons and appear rounder. Lemons are shaped more like an oval. Both are known for a tart flavor, with lemons tasting somewhat sweeter in contrast to a lime’s bitterness.
These two citrus fruits are also used similarly for culinary purposes. Typical uses include sauces, salad dressings, beverages, marinades, and cocktails. Lemons are used in both savory dishes and sweet desserts, whereas limes are used mostly in savory cuisine.
