The amaranth microgreen is thin, feathery, and lovely. It has a vibrant red/pink color, which is why chefs love to garnish with these kinds of microgreens. One thing to keep in mind is that amaranth is light sensitive and grows at a slower rate. So, the blackout period must be extended by a few days to allow the plant to grow taller before exposing these types of microgreens to light. As a result, amaranth microgreen is a little difficult for beginners.
