Dark Opal Basil Highlights

Dark Opal Basil is a variety of sweet basil. The 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.

Dark Opal Basil has a very intense basil flavor. In fact, a much more robust and sweeter taste than Genovese.

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

Primarily used as a garnish, you can also use dark Opal Basil microgreens in cooking. The microgreens add Italian flavor to dishes.

Also, try it in cocktails or non-alcoholic drinks.

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 as it doesn’t store well after being washed. Best to wash it just before using it.

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