Dark opal basil has striking deep purple leaves with pink blooms appearing in mid to late summer. Grown as much for its decorative appeal as for its culinary value, this intensely aromatic basil variety has hints of cinnamon, anise, mint and clove and is a beautiful accent to salads or other uncooked summer dishes. Plant where you can enjoy the fragrance as you stroll through the garden. It won an All America Selections award in 1962.
