Tall, striking shrub to 1,5m with bright blue plumes of flowers and crisp, light green leaves. Good coastal shrub for full sun, requires little attention but thrives on regular watering and feeding with slow release 3: 1:5 or organic fertilizer. Cut back after flowering (winter) or to shape as required. Blue salvia is a favorite of many gardeners because it’s a cinch to grow, flowers profusely all summer, and is wonderfully drought tolerant. It’s a great choice for both beds and borders and containers.
