What is amaranth?

Amaranth belongs to the Amaranthaceae family under the genus Amaranthus. There are around 75 species around the world. It’s grown as both an annual or a short-lived perennial plant.

Amaranth is a flowering herb that comes from the same family as beets, spinach and quinoa. It’s found in parts of Africa, Asia, Europe, and North America for its leaves, seeds or flowers.

Some species of Amaranthus commonly called pigweed are considered invasive weeds in some areas as they pose problems to crops. However, amaranth is much more than a weed!

Generally, the amaranth species cultivated for their leaves are unique from those grown for their seeds (or pseudograins). Common species cultivated for the leafy greens are A. tricolor and A. dubius. Varieties grown for their grain include A. hypochondriacusA. caudatus, and A. cruentus.

Amaranth grains were ground up and used along with maize by the Aztecs in the 16th century to make a variety of foods. In Mexican culture, amaranth grains are commonly popped and eaten as a snack or added to cereals.

Today, amaranth remains a popular breakfast for the health-conscious crowd as it’s gluten-free. It’s cooked as a porridge or a rice alternative. Amaranth contains more protein than rice and is also rich in fiber and iron.

Amaranth seeds are used to extract squalene, an emollient compound used in cosmetics.

The Hopi people, a Native American tribe, used amaranth flowers to produce a red dye.

Amaranth greens are a mainstay in Asian and African cultures. They are cooked as a stir fry and served with rice or noodles.

Garnet Red Amaranth is a popular variety used to grow tiny amaranth microgreens or sprouts. These are used as a garnish in salads, soups and sauces.

What are some health benefits of amaranth microgreens? Let’s take a closer look at amaranth microgreens nutrition facts.

According to data from the USDA, here’s the nutritional content of 100 grams of raw amaranth leaves: 23 calories (34 percent from protein, 10 percent from fat, and 55 percent from carbs).

As you can see, amaranth contains a wide range of vitamins and minerals and is good source of amino acids.

Amaranth contains a huge amount of vitamin K in one serving—it contains 950% of the Daily Value based on a diet of 2,000 calories a day! Vitamin K plays a vital role in blood clotting which speeds up the time of wound recovery. Vitamin K also contributes to healthy bones. Adequate vitamin K content can be difficult to come by in most diets.

You’ll also find an abundance of vitamin C. Vitamin C helps protect and maintain the body’s cells; promote healthy skin, blood vessels, cartilage and bones; and helps to heal wounds.

Amaranth is a good source of manganese which helps to create and activate enzymes in the body. These enzymes do a variety of things including breaking down or digesting food.

Folate or folic acid, a vitamin that most people don’t get enough of, is found in amaranth. Folate is vital in creating new cells, an especially important vitamin for pregnant women.

For a leafy green, amaranth is packed with protein. Amaranth greens and microgreens are great for those on vegetarian or vegan diets.

Amaranth also has the following health benefits:

  • High in calcium and magnesium
  • Contains all nine vital amino acids 
  • Contains plenty of antioxidants like carotenoids and chlorophyll along with other phytonutrients such as lutein, zeaxanthin and beta-carotene.

In the microgreens world, amaranth, in particular garnet amaranth microgreens, are one of the healthiest around. A 2012 study conducted by the University of Maryland along with the U.S. Department of Agriculture (USDA) examined 25 varieties of microgreens for their nutritional content.

Specifically, they looked at:

  • Vitamin C (ascorbic acid)
  • Vitamin E (tocopherols)
  • Vitamin K (phylloquinone) 
  • Vitamin A (beta-carotene)

Of the 25 different varieties of microgreens, garnet amaranth was one of the top four microgreens that contained the highest levels of vitamins C, E, A, and K. Others to score high include red cabbage, cilantro, and green daikon radish.

How to grow amaranth microgreens

Now that you know how nutritious this plant is, I bet you want to try growing it at home! While you could plant full-sized plants in your backyard, growing microgreens is great if you don’t have a lot of space, or time.

While there are different types of amaranth, these instructions are for garnet amaranth microgreens.

Let’s gather a few supplies!

You’ll need:

  • Growing tray and cover: Your growing tray should have drainage holes to help you with bottom watering. Use the cover during the blackout phase.
  • Growing medium: Organic potting mix or a growing medium like coconut coir.
  • Amaranth microgreen seeds: You use about 1 ounce (28 grams) of seed per each 10 X 20 inch grow tray. There’s no need to pre-soak the seeds.
  • Water mister

Ready to harvest: 8–12 days

Notes: This microgreen likes to stay warm. Keep it in a warm spot to help kickstart the germination process. Afterwards, provide light, but keep out of direct sunlight.

  1. Prepare growing medium. Fill the growing tray with 1–2 inches (2.5–5.1 centimeters) of potting mix or growing medium. Thoroughly moisten the growing medium. It should feel moist, but not too soggy.
  2. Broadcast seeds. Spread an even layer of microgreens seeds across the surface of the soil. Use your hands, or a small piece of cardboard to gently press the seeds into the soil. Give the seeds a gentle mist with water.
  3. Place cover on. Now it’s time to begin the blackout/germination phase! Place a cover over the seeds and place in a dark place at room temperature. Continue to mist as needed once a day remembering to replace the cover each time. Germination takes place in 2–3 days.
  4. Bring into the light. Once you see signs of growth you, can remove the cover (on days 3–4) and place near a sunny window (but away from direct sunlight), or under grow lights.
  5. Water. Keep your microgreens happy and healthy by bottom watering them once or twice a day. Simply fill a larger tray, basin, or a clean sink with about 1/2-inch (1.3 centimeter) of water. Place your tray of microgreens into the water for several minutes. This helps to ensure they are evenly watered and protects the fragile shoots at the same time.
  6. Harvest. Your garnet amaranth microgreens will look lovely at this point with their vibrant leaves and stems ranging from fuchsia to deep burgundy. Harvest according to taste, typically between 8–12 days. Use a pair of sharp scissors or a knife and snip just above the surface of the soil.

Enjoy your microgreens fresh and harvest right before eating. Give them a quick rinse beforehand!
