Amaranthus tricolor
vegetableRed Leaf Amaranth is the edible leaf form of Amaranthus tricolor, the leafy green known across the Caribbean as callaloo and across Asia as Chinese spinach or tampala. It is grown for its vivid, often red-and-green leaves, which cook down mild and tender like a richer spinach. Fast, upright, and heat-loving, it thrives in hot weather and poor soil where temperate greens fail, making it a dependable summer leaf crop. The same species also yields edible seeds, and many ornamental and culinary varieties exist - they differ mostly in leaf color and size and share the same easy care. Note this is cultivated edible amaranth, distinct from the weedy wild pigweeds.

Amaranth is a warm-season crop that loves heat: sow only after frost has passed and the soil is warm. The seed is tiny, so sow it shallowly, barely covering it (about a quarter inch), and thin seedlings to 12 to 18 inches apart for full plants, or grow closer and cut young for leaves. Give it full sun (a little late-afternoon shade is fine in extreme heat) and well-drained soil; it tolerates poor soil and is heat- and drought-resistant, but dislikes staying wet and can get root rot if overwatered. Go easy on fertilizer - excess nitrogen dulls the leaf color and is not needed. It grows fast and is very low-maintenance, regrowing after cut-and-come-again leaf harvests.

Leaf amaranth is fast, with tender leaves ready to pick in roughly 30 to 50 days. Snip young leaves and shoot tips as you need them and the plant rebranches for repeat cut-and-come-again harvests; younger leaves are the most tender. Cook the leaves like spinach - they wilt quickly in a saute, soup, or stir-fry. As with spinach, the leaves contain oxalates and can take up nitrates if heavily fertilized, so cook them rather than eating large raw quantities, and do not over-fertilize.
Amaranth leaves are very low in calories and notably rich in vitamins A, C, and K, plus calcium, iron, manganese, and fiber - one of the more nutrient-dense leafy greens. Cook them like spinach in callaloo, stir-fries, soups, and curries; brief cooking softens the leaves and reduces oxalates.
