Seven years ago a new canna lily from South Africa took the gardening world by storm. 'Tropicanna' canna features bright orange flowers and multicolored leaves with pink, yellow, red, orange, and green stripes.
Now two new versions of this popular tropical plant are on the scene. 'Tropicanna Black' and 'Tropicanna Gold' have the same growth characteristics as the original 'Tropicanna', but different colored leaves and flowers. 'Tropicanna Black' features purple-black leaves and bright red flowers. 'Tropicanna Gold' has golden yellow flowers and leaves with green and yellow stripes.
All three cannas grow 6 feet tall at maturity -- smaller when grown in containers. They grow best in full sun on well-drained, fertile soils. Because they're tropical plants, the bulbs need to be dug and stored in fall in areas where the ground freezes in winter.
