Lentil
Lens culinaris
Overview
One of humanity's first cultivated crops, lentils have been feeding civilizations for over 10,000 years since the Fertile Crescent. These tiny but mighty legumes are one of the fastest-cooking pulses, needing no soaking and ready in 20-30 minutes. Red, green, black, and French (Puy) lentils each have distinct textures and culinary applications.
Growing Conditions
How to Grow Lentil
Lentil (Lens culinaris) is an annual graminoid that grows to about 1.5 feet tall and 10 feet wide.
To grow lentil, give it full sun. It is hardy across USDA hardiness zones 7–11. Plant it in well-drained, sandy or loamy soil; drought-tolerant, at a slightly acidic pH of 6–7. It does best with dry, sharply drained conditions.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Its flowers appear from April through July, offering high value to pollinators. Settle it in its first year, and drought becomes its problem to solve, not yours.
Companion Planting & Soil
Lentil grows well alongside barley, oats, flax, and mustard — but keep it clear of onion and garlic.

When to sow, transplant, and harvest by growing zone.
| Zone | Action | Months | Notes |

| Moderate (5-7) | Harvest | May — Jun | Harvest before summer rain; needs dry cure |
| Warm (8-9) | Direct Sow | Oct — Nov | Fall sow for winter/spring crop; cool weather preferred |
| Warm (8-9) | Harvest | Feb — Apr | Spring harvest from fall sowing |

Uses
In the Kitchen
In the kitchen, lentil turns up in more than one form: dal (lentil stew) in Indian cuisine; soups, salads, and stews across global cuisines; french lentils hold shape beautifully in salads.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: high in folate, iron, and plant protein; fiber-rich for cardiovascular and digestive health; low glycemic index for blood sugar management. These are traditional uses, not medical advice.
Beyond the Garden
Lentil earns its keep past the plate, too: nitrogen-fixing crop rotation legume; drought-tolerant food security crop.
