Green Picasso Canna Lily (Canna indica ‘Green Picasso’) is a compact, upright rhizomatous perennial admired for its large yellow flowers finely speckled with orange and sometimes edged in red. These multicoloured blooms stand out brilliantly against light green, subtly variegated foliage, enhancing the plant’s exotic appearance. From July to September, it forms a luminous clump reaching 60 to 90 cm (24 to 36 in) in height and flowers generously until the first cold weather arrives. Its vibrant colour contrast immediately draws attention. 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 30 to 40 cm (12 to 16 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.

‘Green Picasso’ canna lily is ideal for tropical flower beds, borders, patios, large containers, and exotic garden displays. For container growing, choose a pot at least 40 cm (16 in) in diameter with excellent drainage. Its yellow, orange, and red flowers pair beautifully with caladiums, alocasias, coleus, begonias, and ornamental grasses to create lush, colourful displays. The blooms 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.

Sowing guide

It all startswith a seed.

Sowing depth

10 cm (4 in)

Sowing period

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 30 to 40 cm (12 to 16 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 cool, 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 and flowering.

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

40 cm (16 in)
Container gardening requires planning for the volume needed for roots and the plant's final height. Choose a stable pot with drainage holes and a suitable growing medium. Leave enough space to respect recommended depth and spacing, rather than crowding plants to immediately fill the pot. Place the container in the indicated exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting directly in the ground. Therefore, plan from the outset for a wintering location compatible with the plant's needs and your region's climate. 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. In a container, 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 in the ground.
