Canna ‘Bronze Louise Cotton’ (1 rhizome)

Louise Cotton Bronze Canna Lily (Canna generalis Louise Cotton) is a remarkable rhizomatous perennial distinguished by its rich dark bronze foliage, composed of large, elegant leaves that create a structured tropical presence. From July to September, soft cream-yellow to pale yellow flowers rise gracefully above the dark foliage, creating a refined and luminous contrast. Reaching approximately 130 cm (52 in) in height, this variety brings warmth, vertical interest, and elegance to summer landscapes. Its striking foliage remains highly ornamental even before flowering begins. Hardy only to Zone 10, it must be protected from frost in Quebec.

Plant the rhizomes in spring after all danger of frost has passed and the soil has warmed thoroughly. Position them horizontally, approximately 10 cm (4 in) deep, and space them 40 to 50 cm (16 to 20 in) apart. Choose a location in full sun with rich, fertile, organic, evenly moist, and well-drained soil. Water generously throughout active growth to maintain consistent moisture without allowing standing water. Regular applications of compost and a balanced fertilizer every two weeks encourage vigorous growth and abundant flowering. Before the first frost, lift the rhizomes and store them in a cool, dry place.

Louise Cotton canna lily is ideal for tropical flower beds, borders, patios, large containers, and exotic gardens. For container growing, choose a pot at least 45 cm (18 in) in diameter with excellent drainage. Its dark bronze foliage pairs beautifully with caladiums, alocasias, coleus, begonias, and ornamental grasses to create lush, high-contrast plantings. The soft cream-yellow flowers attract a variety of pollinators and may also be used in summer floral arrangements. However, they are grown exclusively for ornamental purposes and are not intended for consumption.
