O. Basilicum, var.This All America Award winner for 1987 looks remarkably like a miniature perilla. Leaves are much darker than regular opal basil and the plant is larger, 18 to 24 inches. The flower stalk of 6" with pink blooms is more dramatic than other basils. Like opal basil, it can be used as both an ornamental and culinary herb. Flavor is good and the color adds drama to garnishes and herbal vinegars. 100 seeds.
