Dark Opal Basil Seed

(2 customer reviews)


The flavor of Dark Opal Basil, in my opinion, is sweeter than Genovese Basil and has a beautiful variegated maroon leaf.

This microgreen is more interesting and tastes better than your basic green sweet basil.

Use Dark Opal Basil microgreens for cooking, salads, and garnish. Also, try it in cocktails or non-alcoholic drinks.

Sold in packages with the correct weight for the Home Microgreens Tray, 5- by 5-inch trays, 10- by 10-inch trays, and the ounce.

Dark Opal Basil is a variety of sweet basil. Young true leaves and the insides of more mature leaves have a dark maroon color. The veins of the leaves also stay dark, giving this basil a variegated look.

As a microgreen and baby salad, Dark Opal Basil has a very intense basil flavor. In fact, a much stronger and sweeter flavor than Genovese.

For a beautiful Caprese salad, mix young Dark Opal, Red Rubin, and Genovese Basil leaves with tomatoes and fresh mozzarella cheese!

Mostly used as a garnish, Dark Opal Basil microgreens can also be used in cooking. Adds Italian flavor to dishes.

Dark Opal Basil seed is mucilaginous, meaning that it develops a jelly-like coating when it gets wet. Basil loves the light and will do better in a well-lit location. Heat mats will also speed up the germination and growth of basil.

Try to harvest basil clean; it doesn’t store well after being washed. Best if you wash just before using it.

Dark Opal Basil grows a bit quicker than Genovese Basil in my experience.
