Whether you raise these special cannas in a summertime perennial border or a feature bed, they will yield many large blooms in a variety of tropicallooking colours. Starting in summer and continuing through fall's first frost, the flowers just keep on coming, borne on towering stalks that reach up to 5' high. Despite their exotic appearance, cannas are very adaptable and perform well in most types of soil. Covers 20-22 sq ft when planted together.
