Give a boggy spot a splash of vivid color with a trio of cannas: Tropicanna, Tropicanna Gold and Tropicanna Black. These cannas unfurl striking leaves that boast a variety of vibrant tropical colors and patterns. Luxuriously large flowers accent the calypso colored leaves for an exotic show. Plants grow 4 to 6 feet tall. Hardy in Zones 7-11. Lift rhizomes in colder zones to store overwinter.
