Canna 'Black Knight' is known for its deep burgundy foliage and bold red flowers. Growing to about 4 to 6 feet tall, it thrives in full sun and prefers moist, well-drained soil. Blooming from mid-summer until frost, it adds dramatic color and texture to gardens, borders, and containers. Hardy in zones 7-11, it requires lifting and storing in colder climates before winter. This variety is particularly effective in mass plantings, poolside landscapes, and as a focal point in tropical-themed gardens.
