Gardengnome's Garden
Canna x generalis
Genus: Canna.
Species: Canna indica.
Heat and sun-loving plants, Canna's brightly colored spikes of flowers and bold banana-like leaves create a dramatic, tropical effect. Varieties range from very dwarf (18-20") to tall (more than 4 feet, with red, yellow, orange, apricot, salmon, white, bicolor, spotted and streaked flowers. Use dwarf Cannas as bedding plants or in large containers as accents. Use leaves in flower arrangements though cut flowers don't last. Plant rhizomes after soil has warmed. Best in rich soils with plenty of moisture. Some varieties are grown in water or very wet soils. In zones 7 or colder, dig up rhizomes in fall, and store them in a moist, frost free place.
