Amaranth

Overview

An ancient grain revered by the Aztecs as a sacred food, amaranth is both a stunning ornamental and a nutritional powerhouse. Its towering flower plumes in deep red, gold, or green are dramatic in the garden, while its tiny seeds contain more protein than most grains. Both the leaves and seeds are edible, making it a dual-purpose crop for food-forest gardens.

How to Grow Amaranth

Plant it in fertile, well-drained soil; tolerates poor conditions once established, at a slightly acidic pH of 6–7.5.

Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. The details above are a starting point — your ground will teach you the rest.

Companion Planting & Soil

Amaranth grows well alongside corn, onion, potato, and tomato.

Uses

In the Kitchen

In the kitchen, amaranth turns up in more than one form: seeds popped like popcorn or cooked as porridge; young leaves used like spinach in salads and stir-fries; ground into flour for gluten-free baking.

Medicinal & Folk Use

In herbal and folk tradition, it has been valued in several ways: complete protein source with all essential amino acids; high in iron, calcium, and magnesium; leaves rich in vitamins A and C. These are traditional uses, not medical advice.

Beyond the Garden

Amaranth earns its keep past the plate, too: natural dye from red-pigmented varieties; ornamental dried flower arrangements; grain crop for food sovereignty projects.
