Botanical nameCanna × generalis ‘Wyoming’
Wyoming Bronze Canna Lily (Canna × generalis ‘Wyoming’) is a spectacular tropical perennial distinguished by its broad, dark bronze leaves with rich copper highlights. From July to September, bright orange flowers rise in airy clusters above the dark foliage, creating a warm and luminous contrast. Its rapid growth and vigorous silhouette, reaching approximately 150 cm (60 in) in height, instantly bring structure, depth, and tropical character to summer landscapes. Not hardy in Quebec, this canna is grown as a seasonal plant, while its rhizomes are stored in a frost-free location and replanted the following spring.
Grow ‘Wyoming’ canna lily in full sun in rich, fertile, organic, evenly moist, and perfectly drained soil. Plant the rhizome horizontally in spring after all danger of frost has passed, approximately 10 cm (4 in) deep, and space plants 40 to 50 cm (16 to 20 in) apart. Keep the soil consistently moist with generous watering, without allowing standing water. Apply a balanced fertilizer every two weeks to support vigorous growth and abundant flowering. Remove spent flowers, then lift the rhizomes before the first frost and store them in a cool, dry place.
With its majestic appearance, ‘Wyoming’ canna lily becomes an outstanding focal point in tropical flower beds, generous borders, exotic gardens, and large containers measuring at least 45 cm (18 in) in diameter. On a patio, its copper-bronze foliage creates a lush display, while its bright orange flowers add vibrant colour until the first frost. Pair it with caladiums, alocasias, coleus, begonias, or ornamental grasses to create richly textured, high-contrast plantings. Its flowers also attract a variety of pollinators and may be used in summer floral arrangements, although they are not intended for consumption.

Best planting time
Spring
Propagation
Propagate by dividing the rhizomes in spring once they have several growing buds. This ensures plants remain true to the variety.
Growing method
Plant the rhizomes in spring after all danger of frost has passed, approximately 10 cm (4 in) deep in rich, fertile, well-drained soil. Position the rhizome horizontally before covering it with soil. Space plants 40 to 50 cm (16 to 20 in) apart. Choose a location in full sun. Water thoroughly after planting, then keep the soil consistently moist throughout the growing season. Lift the rhizomes before the first frost and store them in a dry place until spring.

Container growing
Container growing
Recommended pot size
45 cm (18 in)
For Canna 'Wyoming', container cultivation requires providing enough volume for both the roots and the plant's final height. Choose a stable pot with drainage holes and a substrate suitable for planting. Leave enough space to respect the recommended depth and spacing, rather than crowding the plants to fill the pot immediately. Place the container in the indicated exposure and check the moisture level regularly, especially in hot or windy weather. A pot is more exposed to temperature fluctuations than planting in open ground. Therefore, plan ahead for an overwintering location compatible with the plant's needs and your region's climate. Plant the canna rhizomes in the spring in warmed soil, after the frosts. Choose a sunny location sheltered from winds that could tear the large leaves. Prepare soil that is fertile and loose enough for roots to develop around the rhizome, then place the buds facing upward. Water after planting and monitor moisture during the initial growth phase. Once the leaves have developed, waterings should correspond to growth and the weather. In containers, choose a volume adapted to the mature plant and keep the drainage holes clear, without letting the roots dry out completely between waterings.
