This 3-foot-tall canna from the 1920s has impossibly deep, pure-rose flowers recalling orchids and leis. It's an old French variety.

Each of this plant's stunning lance-shaped leaves is the softest gray-green, edged subtly with a cream-colored pinstripe. These luminous 5-foot-tall plants are crowned with spires of delicate pink flowers with just a blush of salmon.

A great canna to start with if you're convinced you hate them is 'Madame Paul Caseneuve', from 1902. The pearly-bronze leaves and almost purple stems of this 3- to 5-foot-tall antique beauty are the perfect foil for its elegant, sensual flowers of soft pink shading to peach and apricot.

'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.

Growing to 6 or 7 feet, 'Sémaphore' features slender, dark-bronze leaves topped by spikes of narrow-petaled flowers of an unusual glowing color that's not quite yellow and not quite orange; perhaps flickering tongues of flame would be the best description. It is a Victorian classic from 1895.

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.
