Scarlet flower clusters rise above dense green leaves on Canna generalis Robert Kemp, creating a tall focal point from midsummer into early fall. Hummingbirds and other pollinators visit the blooms.
This clump-forming perennial works well in beds, mass plantings, or large patio containers. Plant it in full sun to partial shade with rich, moist, well-drained soil, and water regularly during active growth.
In cold-winter gardens, lift and store the rhizomes after frost. Divide crowded clumps as needed.
