Canna Lily Plant

Garden canna, commonly called canna lily, is a rhizomatous perennial valued for large leaves and brightly colored flowers. Flower and foliage colors vary among cultivars, so a general garden-canna entry should describe the broad group rather than imply a single color or selection. ## Form and siting The [North Carolina Extension Plant Toolbox](https://plants.ces.ncsu.edu/plants/canna-x-generalis/) describes Canna × generalis as the name used for garden hybrids, with erect, clumping growth, plants reaching up to 6 feet, and colors varying by cultivar. Its dimensions span 2–6 feet tall and 1–2 feet wide; it recommends full sun to partial shade and moist, well-drained soil with high organic matter. ## Seasonal care Plant rhizomes after the last spring frost and water through active growth. Spent flowers can be removed to encourage continued summer flowering. In warm regions, rhizomes may overwinter in the ground with mulch; in colder climates, lift them after frost and store in a cool, dry place for winter. ## Maintenance Cut frost-damaged foliage down after the first frost. Lift and store rhizomes where winters are too cold for them to remain in the soil, then replant after frost danger passes.
