What does Amaranth look like?
Amaranth plants can grow from 1 to 2.5 metres tall, with hollow, succulent stems that may be green or reddish. Their leaves are oval or elliptical, 6.5 to 15 cm long, and can be arranged opposite or alternate. The flowers are tiny, packed densely in large, tassel-like clusters called panicles, which can be erect or bent. Flower colours range from green to maroon and crimson, and the plant produces small, shiny seeds in capsules. Some species have spiny stalks.
Where does Amaranth come from?
The genus Amaranthus most likely began in Central America and is now found across tropical regions worldwide, from lowlands to mountain ranges like the Himalayas. Amaranth was cultivated by ancient peoples in the Americas, including the Aztecs, who called it huāuhtli. Archaeological finds show amaranth grain was used in Mexico and Argentina thousands of years ago. The name 'amaranth' comes from Greek, meaning 'unfading', and was first used in Europe for a related plant, Celosia.
When and how Amaranth blooms
Amaranths bloom in summer or autumn, producing dense flower clusters. They grow quickly from seed and can thrive in a range of soils and climates. Some species are annual, others perennial. Seeds are sown directly, and the plants develop a deep root system. The grain is harvested about 200 days after planting, with each plant producing thousands of small seeds. Both leaves and seeds are collected for food.
How Amaranth is used
People use amaranth as a leafy vegetable, a grain crop, and an ornamental plant. Its seeds are ground into flour or cooked whole, and its leaves are eaten as greens. In the United States, amaranth is mostly grown for seed, used in cereals and baked goods. Some species are considered weeds in agriculture, while others are valued for their colourful flowers in gardens.
Kinds of Amaranth
There are about 75 species of Amaranthus, with wide differences in flower form, colour, and plant size. Some, like A. caudatus, A. cruentus, and A. hypochondriacus, are grown for grain. Others, such as A. palmeri, are known as weeds. The genus includes both monoecious (male and female flowers on one plant) and dioecious (separate male and female plants) species.
What Amaranth means
Amaranth has deep cultural roots, especially in Mexico and Central America, where it was a staple food for the Aztecs. Its name means 'unfading flower' in Greek, reflecting its long-lasting blooms.
