what are trueleaf stages?

An industry first, MicroGenesis has created our unique trueLEAF Stage grading system out of necessity.

Microgreens first hit the market as early as the 1990's in the United States, and even earlier than that in European markets. Unfortunately, the scientific research for microgreens is lacking, resulting in no defined stages of harvestable maturity.

Currently, microgreens may be defined as any crop harvested immaturely for the fresh and whole consumption of its hypocotyl (stem), cotyledons (first "seed" leaves), and true leaves, up to the emergence of the third true leaf. During growth, the emergence of new morphological features, such as the emergence of new leaves, on a microgreen may affect multiple attributes of the product, such as taste, texture, appearance, and shelf life. 

We knew that in order to ensure a consistent product for our customers, we had to develop a grading system to properly identify these different growth stages. This way, whenever you buy microgreens from MicroGenesis, you will know exactly what stage you are purchasing and what flavors, colors, and textures you can expect. 

 

What is a True Leaf? 

TRUE LEAF STAGE GRAPHICS-01.png

no True Leaf

No true leaves have appeared. Very young and tender.

TRUE LEAF STAGE GRAPHICS-02.png

One true leaf

First true leaf has appeared. More color and flavor develop.

TRUE LEAF STAGE GRAPHICS-03.png

two true leaves

Two true leaves have formed. Most vibrant color, less tender.

Stage 0-1

Stage 0- 1 is the initial stage of growth. These are the most tender microgreens with no true leaves or one true leaf. You will find these to be less fibrous, and more delicate than stage 1-2, but they won't lack in flavor. While the flavors present might be more delicate than the further stage of growth, these microgreens will still have an impactful effect. You can expect bright vibrant colors, however, stem color might be lighter than at stage 1-2.

Stage 1-2

Stage 1-2 is a more developed growth stage. These are microgreens with one or two true leaves. The texture of this stage is more robust and harder than younger greens. The flavor is incredibly impactful and at it's most developed. You can expect a small amount to go a long way. Similar to stage 0-1, the color in all of our microgreens is incredibly vivid, however, you might see more color development in the stem at this stage.
