Dark Opal Basil (Ocimum basilicum) is a sweet basil variety celebrated for its regal, purple-black glossy foliage and pale pink flowers. This basil is as flavorful as it is visually stunning, with a rich aroma that enhances a variety of dishes, from flavored vinegars and oils to pesto and pasta. The deep purple leaves not only bring a burst of color to your meals but also make this plant an excellent choice for ornamental gardening.
Dark Opal Basil is perfect for adding to your pollinator garden, as its beautiful pale purple flowers attract bees and other beneficial insects. The contrast of the dark leaves and stems with the delicate flowers makes it a striking addition to bouquets. Growing to a height of 12-18 inches, this basil is slow to bolt, low maintenance, and easy to cultivate, making it ideal for containers, window boxes, bedding, or borders.
