Botanical nameCanna × generalis ‘Red King Humbert’

Red King Humbert Bronze Canna Lily (Canna × generalis ‘Red King Humbert’) is a vigorous rhizomatous perennial distinguished by its impressive dark bronze foliage with rich purple undertones. Its large, glossy leaves create a bold, tropical, and architectural silhouette that reaches approximately 150 cm (60 in) in height. From July to September, brilliant bright red flowers rise in luminous spikes above the dark foliage, creating a dramatic and eye-catching contrast. This variety brings depth, warmth, and striking colour to summer landscapes. 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.

‘Red King Humbert’ 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 brilliant red 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.

Planting guide

Plant well.Grow beautifully.

Planting depth

10 cm (4 in)

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.

Soil and care

The right care,at the right time.

Soil pH

Neutral to slightly acidic

Minimum temperature

5°C (41°F)

Care level

Easy

Watering

Water generously throughout the growing season to keep the soil consistently moist without allowing standing water.

Soil type

Rich in organic matter, fertile, evenly moist, and perfectly drained soil.

Fertilization

Apply a balanced fertilizer every two weeks during the growing season. Regular applications of compost also improve plant vigour.

Seasonal care

Remove spent flowers regularly to extend blooming. Keep the soil consistently moist throughout the growing season. Feed every two weeks. Lift the rhizomes before the first frost and store them in a cool, dry place.

Container growing

A garden,within reach.

Recommended pot size

45 cm (18 in)
Container gardening requires planning for the volume needed for the roots and the plant's final height. Choose a stable pot with drainage holes and a suitable growing medium. Leave enough space to respect the recommended depth and spacing, rather than crowding plants to immediately fill the pot. Place the container in the indicated exposure and check the moisture regularly, especially in hot or windy weather. A pot is more exposed to temperature variations than a plant in the ground. Therefore, plan for a wintering location compatible with the plant's needs and your region's climate from the outset. Plant canna rhizomes in spring in warmed soil, after the last frosts. Choose a sunny location sheltered from winds that could tear the large leaves. Prepare fertile and loose enough soil for the roots to develop around the rhizome, then place the buds facing upwards. Water after planting and monitor moisture during establishment. Once the leaves have developed, watering should follow growth and weather conditions. For container planting, choose a volume appropriate for the mature plant and keep the drainage holes clear, without letting the roots dry out completely between waterings. In winter, protect the container according to the plant's needs: its roots are more exposed to cold than when planted in the ground.
