The large leaves are bluish purple and highly aromatic. Looks wonderful in a pot together with a large-leaved green basil plant. Also very popular as a sprout vegetable. Produces purple blooms at the end of the season. Delicious in rice dishes, etc. and decorative in basil vinegar. Sow in a greenhouse. Do not cover the seeds. Press them gently and keep moist. Once the plants are large enough, transplant into pots and boxes, or in a warm spot in the garden.
