Cannas are spectacular summer bulbs. Paddle-shape leaves wrap in ruffles around stems, tapering to refined buds. The buds open into eye-catching flowers of red, orange, yellow, and pink from late spring or early summer to first frost. Cannas are commonly referred to as “bulbs,” although they are not true bulbs. They multiply beneath the soil from a rhizome, an underground stem. The red cannas are from Hickory whereas the golden ones are from Santa Monica, California.
