Are there non-edible microgreens?

Did you know that not all microgreens are edible? Microgreens have gained immense popularity for their nutritional value, vibrant colors, and intense flavors. However, there are certain microgreens that are grown purely for decorative purposes and are not meant to be consumed. In this article, we will explore the fascinating world of microgreens and discover which varieties are strictly non-edible. So, if you’re curious to learn more about these tiny greens, read on to uncover the lesser-known side of microgreens.

What are microgreens?

Microgreens are young, tender greens that are harvested just a few weeks after germination, when they are approximately 1-3 inches tall. They are more mature than sprouts but smaller than fully grown plants, making them the perfect size for adding a burst of flavor, color, and texture to dishes. Microgreens are known for their intense flavor profiles and nutrient density, making them a popular choice among chefs, health enthusiasts, and home cooks alike.
