Dark Opal Basil leaves

Dark Opal Basil is a cultivar of basil (Ocimum basilicum) known for its striking dark purple leaves and aromatic properties. It is a popular herb in culinary applications and is also used for ornamental purposes due to its unique coloration.

Description

Dark Opal Basil is characterized by its deep purple leaves, which can sometimes appear almost black. The plant typically grows to a height of 12 to 18 inches and has a bushy habit. The leaves are smooth and ovate, with a slightly glossy texture. The flowers of Dark Opal Basil are small and pink to lavender in color, appearing in clusters at the top of the stems.

Cultivation

Dark Opal Basil thrives in warm, sunny environments and requires well-drained soil. It is sensitive to cold and should be planted after the last frost date in spring. The plant benefits from regular watering but should not be overwatered, as this can lead to root rot. Pinching back the stems encourages bushier growth and prevents the plant from flowering too early, which can reduce leaf production.

Uses

Culinary

Dark Opal Basil is used in a variety of culinary dishes. Its flavor is similar to that of sweet basil, with a slightly spicier and more pungent taste. It is often used in pesto, salads, and as a garnish. The leaves can also be used to infuse oils and vinegars, imparting both flavor and color.

Ornamental

Due to its vibrant color, Dark Opal Basil is often used in ornamental gardens. It provides a striking contrast to green-leaved plants and can be used in borders, containers, and as a decorative element in herb gardens.

History

Dark Opal Basil was developed in the 1950s by John Scarchuk and Joseph Lent at the University of Connecticut. It was the result of a breeding program aimed at creating a basil variety with ornamental appeal. The cultivar was awarded the All-America Selections award in 1962 for its unique appearance and versatility.
