Amaranth is a common and highly nutritious weed easily recognised by its beautiful but rather peculiar nodding seed heads.

What Is Amaranth?

Amaranth (Amaranthus retroflexus) is an ancient grain, one of the first domesticated wild plants in Southern America, cultivated for at least 8000 years. High in iron, protein, magnesium and potassium, its value was recognised in ceremonies by the Aztec civilisation and mirrored today by its status as a so-called superfood.

There are about 70 species of amaranth, all edible, and many of them have become successful colonisers (or weeds), making it a reliable food source in many cultures. Many of the species turn into tumbleweeds, helping the spread of the seed. Amaranth is eaten all around the world including South India, where it is known as kuppacheera; Greece (called vlita) and China (called yin choi).

Identifying Amaranth

Amaranth is a branched herb that grows from seeds each year. It can range from an erect shrub up to two metres tall, to a wide prostrate ground cover. The diamondshaped leaves have long stalks and vary from the bright emerald of Green amaranth to the three colours of the Tricolour amaranth: green, yellow and red. It forms a cluster of flowers resembling a sharp cone or spike which emerges from the intersection between the main leader and the stalks. The flower clusters increase in size and frequency at the top of the plant and can be quite showy, ranging in colour from green to yellow through to deep red. The uppermost cluster of flowers is the biggest.

It is often heavy with seeds in tassels resembling thick, cat-like tails. The flowers are tiny and the seeds, which range in colour from yellow through to black, are small. It can be hairy and in the case of Spiny amaranth (Amaranthus spinosus), two visible thorns will emerge from the base of each leaf.

How To Eat It

Many cultures both cultivate and wild harvest leaves and grains, including Indigenous Australians. According to the Australian National Botanic Gardens, there are 11 native species of amaranth.

The most common varieties found in south-east Australia are Green Amaranth (Amranthus viridis), White amaranth (Amaranthus allbus) and the natives known as Native amaranth (Amaranthus interruptus) and Boggabri weed (Amaranthus mitchellii). All of them are edible.

Amaranth is mostly known for its seeds which, although just one millimetre in diameter, are relatively easy to harvest by rubbing the dry flower heads and allowing the hull-less seeds to fall into a fine colander. The seed can be cooked whole, but is advised to either crush them in order to break the skin which will help to facilitate easier digestion.

The leaves are harvested green and cooked like spinach in pies, soups and stews, and the leafy stems and flower clusters are similarly used.

Lost And Found

Amaranth Was Outlawed For Hundreds Of Years

Although cultivated and eaten in India, China and Australia, the original strain of pre- Colombian civilisation’s Amaranth was nearly lost. When the Spanish conquistadores invaded the Americas, they outlawed the use and cultivation of the plant, calling it ungodly pagan food. They burnt crops and punished anyone found using it, including cutting off the hands of anyone who planted it. And so the grain went underground for 300 years until it was rediscovered in the 1970s, when researchers found it high in the mountains of Mexico and reintroduced the ancient species.
