This vigorous 5- to 6-foot plant sports fascinating foliage colors. Spring leaves emerge an intense purple and are soon striped with green, yellow, pink, and red. Vivid orange flowers appear in summer on this quick multiplier.

Cannas bear broad, smooth paddle-like leaves reminiscent of banana plants. The oversize leaves make it easy to create dramatic combinations with other, more finely textured plants. Each stout, fleshy stem is topped with attractive spires of brightly colored flowers. Cultivars vary widely in height, foliage, and bloom.

'Pretoria' is perhaps the showiest of all of the variegated cannas and one of the best for hot, humid, sunny southern gardens. Favored for its bright green and yellow variegated foliage and deep tangerine flowers, 'Pretoria' will grow at the edge of ponds in shallow water as well as in normal garden conditions. It is adaptable to heat and humidity. Protect in the northern part of its range, or lift tubers in fall where not hardy and store over winter.

A tropical tree by design, the Mexican fire bush freezes to the ground in winter in Zones 8-11, but grows up to 5 feet tall by summer's end. The erect, branched, woody stems bear simple copper-toned leaves with small orange flowers bunched along the tips. It loves the heat, and the more you can give it, the more vigorous it will be.
