Opal Basil, scientifically known as Ocimum basilicum ‘Dark Opal’, is a fascinating herb that adds a touch of elegance to any garden or landscape. One of the first things to note about Opal Basil is that it is typically grown as an annual or biennial plant. This means that it completes its life cycle within one or two years, making it perfect for seasonal displays or continuous cultivation.
The allure of Opal Basil lies in its striking foliage, which features deep purple leaves that almost appear black. These unique leaves create a visually stunning contrast in any garden setting, particularly when planted alongside other green or flowering plants. The dark coloration of the leaves is truly eye-catching and can add a touch of drama to any landscape design.
In addition to its striking appearance, Opal Basil also offers a delightful licorice scent. This aromatic fragrance adds another layer of sensory interest to the plant, making it even more appealing to gardeners and visitors alike. The scent of Opal Basil can be enjoyed simply by brushing against the leaves or by crushing them gently between your fingers.
During the summer months, Opal Basil produces attractive spikes of small, tubular cerise flowers. These flowers are arranged in whorls, creating a visually appealing display above the foliage. The vibrant color of the flowers, combined with the dark purple leaves, creates a striking contrast that is sure to draw attention and admiration from anyone who beholds it.
Now, let’s address the question of whether Opal Basil is a perennial or an annual. As mentioned earlier, Opal Basil is typically grown as an annual or biennial plant. This means that it completes its life cycle within one or two years, respectively. However, it is worth noting that in certain climates or growing conditions, Opal Basil may exhibit some perennial characteristics.
In warmer regions with mild winters, Opal Basil may survive and continue to grow for multiple years, behaving more like a perennial. In such cases, the plant may develop a woody stem and continue to produce new growth even after the initial year or two. However, it is important to remember that Opal Basil is not considered a true perennial in most regions and is primarily cultivated as an annual or biennial.
To summarize, Opal Basil, or Ocimum basilicum ‘Dark Opal’, is a captivating herb that adds beauty and fragrance to any garden or landscape. With its deep purple, almost black leaves and delicate licorice scent, it is a standout choice for both visual and sensory appeal. While typically grown as an annual or biennial, it may exhibit some perennial characteristics in warmer climates. Regardless of its lifespan, Opal Basil is a wonderful addition to any garden, offering an enchanting and unique presence that is sure to delight all who encounter it.
