Upright plants grow to 60cm (25″) tall, with strongly aromatic, oval leaves, and growth so vigorous no pinching is needed. Cardinal is very useful as a culinary basil, but wait until it blooms! Dark scarlet flowers make Cardinal such a show stopper that it will dominate your herb bed or flower border. In mid-summer the plants are crowned by surprisingly tall pagoda shaped flower clusters that are fragrant and attractive to pollinators. Try some Cardinal basil seeds in containers in your patio herb garden and enjoy the flavour and colour all summer long. Basil prefers warm weather, good drainage, and full sun.
