The early-blooming ‘Cannova’ series of cannas are great as “thrillers” in landscapes and containers. ‘Bronze’ varieties have bronze foliage; all others have green leaves. Most are 30-48 inches tall, spread 14-20 inches. Available in gallon pots. New for 2024: Cannova Rose Dark Bud, which is the first compact plant within the Cannova line at 18-36 inches tall.
