Ocimum basilicum Dark Opal (Basil)

Noted for its striking foliage and delicate licorice scent, Ocimum basilicum 'Dark Opal' (Basil) is an annual or biennial herb with stunning deep purple, almost black leaves. In summer, attractive spikes of small, tubular cerise flowers arranged in whorls are borne above the foliage. While most basils are grown just for their leaves and flavor, Dark Opal Basil is also very ornamental in the garden. A popular herb for growing at home, both in gardens and containers, it can be used for tomato sauce, spaghetti, stews, fish, vinegars and salads.
