Lentil (Lens culinaris): plant, seed, and culinary pulse

Characteristics

Lentil plants are bushy and generally short, often around 30–40 cm (about 12–16 inches) tall. Seeds develop in small pods, typically with one or two seeds per pod. The seeds occur in a range of colors and sizes, from brown and green to red, yellow and black, and their texture and cooking behavior vary accordingly.

History and development

Lentils are among the oldest domesticated crops and have been part of human diets for millennia. They were cultivated early in agricultural societies across the Near East and Mediterranean and later spread to South Asia and beyond, becoming a staple wherever pulses form the basis of plant protein.

Uses and nutrition

Lentils are a dietary staple in many cuisines, commonly prepared as soups, stews, purees (such as dal), salads, or patties. They are prized for their high protein and fiber content, low fat, and micronutrients such as iron and folate. Typical culinary forms include whole seeds, split lentils, and flours.

Cultivation and varieties

Grown in temperate to semi-arid climates, lentils are relatively drought-tolerant and fit well in crop rotations because, like other legumes, they help replenish soil nitrogen through biological fixation. Major types include:

• Brown and green lentils — versatile and common
• Red and yellow lentils — often sold split and cook quickly
• Black (beluga) and French lentils — firmer texture and prized for salads

Practical links and notes

For information on cultivation practices see cultivation guides. For classification within legumes consult resources on the legume family. For culinary uses see general vegetable and pulse cookery references. For descriptions of seed shape and anatomy see pages on lens-shaped seeds.

Because of their nutrition, adaptability and role in sustainable farming, lentils remain an important global pulse crop used both at household and commercial scales.
