Getting to Know ‘Dark Opal’ Basil

Table of Contents

First things first, let’s trace back the roots of ‘Dark Opal’ basil. This striking cultivar was meticulously bred by Dr. Joseph M. Lent and Dr. John Scarchuk, two brilliant minds from the University of Connecticut’s Horticulture and Plant Breeding program.

Inspired by Turkish basil varieties with purple and green variegated leaves, the duo decided to create a cultivar entirely in royal purple. After years of selective breeding, ‘Dark Opal’ was born – a visually captivating plant with an equally delightful flavor profile.

Since its release to the market in 1962, ‘Dark Opal’ has garnered widespread popularity among home gardeners. The distinct purple hue of the leaves comes from anthocyanins, the same compound that gives other purple vegetables like eggplants their vibrant color.

Apart from being visually appealing, ‘Dark Opal’ basil provides an earthy, lemon-lime flavor with a hint of crispness. It’s a perfect balance between the traditional sweet basil and the licorice-heavy Thai basil cultivars.

Propagation of ‘Dark Opal’ Basil

Now that you’re intrigued by the allure of ‘Dark Opal’ basil, let’s discuss how you can bring this gem into your garden. There are several methods to propagate this basil cultivar:

Growing from Seed: While this method takes time, it’s cost-effective and allows you to produce multiple plants from a single seed packet. Consider succession planting to ensure a steady supply of ‘Dark Opal’ throughout the summer.
Taking Cuttings: If you prefer a quicker route, consider taking cuttings from an existing plant to propagate new ones.
Dividing Grocery Plants: Although a bit more expensive, this method allows you to harvest leaves sooner than growing from seeds.

Whichever method you choose, ensure you have the necessary tools and knowledge. For a detailed overview of basil propagation, refer to our comprehensive guide.
