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.

From May to frost, whatever the temperature, this plant's creamy yellow markings do not fade. It looks good in containers or in garden beds, and you can use it in the foreground or as a focal point in distant plantings. Variegated tapioca attains a height and width of 3 to 4 feet. It is normally grown as an annual, but can be overwintered indoors. -Allan Armitage, Plant picks, Fine Gardening issue #121

One of the hardiest palms, Chinese windmill palm has single stems with large, 4-foot-wide fans of sword-like leaves. It produces large plumes of yellow flowers in early summer; the flowers of female plants transform into bluish-black fruits. Chinese windmill palms may be shoot-hardy to Zone 6 if protected with 10 inches of mulch. With their rich fans and handsome habits, they make attractive specimens for formal outdoor spaces. These evergreen palms are native to the mountains and temperate regions of subtropical Asia. Plants can grow to 20 feet tall and 8 feet wide.

Tropicanna Gold 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, Tropicanna Gold 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.
