Description
Canna Lily ‘Tropicanna’ (Canna x hybrid, family Cannaceae)
Canna Lily ‘Tropicanna’ is a medium variety celebrated for its dazzling foliage and vibrant blooms. Its lush leaves are streaked with a dramatic blend of green, bronze, yellow and burgundy, creating a tapestry of shifting colours that look striking in any light. Large orange flowers rise above the foliage, adding an extra layer of tropical flair. Typically growing 90–120 cm tall, ‘Tropicanna’ can reach up to 1.8 m in ideal conditions with room to grow, making it a versatile feature for gardens of any size. A long-flowering variety, it blooms from summer to autumn in cooler regions and from spring through to autumn in warmer climates, where the foliage may also remain evergreen. Hardy, resilient, and adaptable, it combines exotic style with reliability.
Where to Plant
‘Tropicanna’ is ideal for garden beds, borders, and large containers, where its brilliant foliage and flowers create an exotic focal point. Its medium height adds structure and colour without overwhelming smaller spaces, while in larger gardens it can be mass-planted for a bold tropical effect. It also performs beautifully beside ponds or pools, where the light brings out the rich tones of its variegated leaves.
Climate Suitability
Canna Lilies are suitable for all climates. In cooler areas, they flower from summer to autumn, while in warmer climates they bloom from spring into autumn and may retain evergreen foliage. These adaptable plants perform best in sheltered, sunny positions with consistent moisture and benefit from protection from strong winds.
When to Plant
Plant in spring once the risk of frost has passed. In frost-free or warmer regions, planting can also be done in late autumn or winter, as the rhizomes will settle and develop roots during the mild season, ready for strong growth in spring.
Soil
Canna Lilies can be grown in a range of soils and can even tolerate damp conditions, but they perform best in rich, well-drained soil with a neutral to slightly acidic pH. Incorporating compost or well-rotted manure will improve fertility and structure, helping sandy soils retain moisture and heavier soils drain more freely. Adding organic matter at planting time sets the rhizomes up for strong growth and abundant flowering.
Location/Position
Choose a full sun to partial shade position. Canna Lilies thrive in full sun, which encourages the best flowering and foliage growth. However, in regions with extreme heat, they benefit from partial shade during the hottest part of the day to prevent leaf scorch. Plant in a sheltered spot that offers protection from wind. While generally medium in height, ‘Tropicanna’ can grow taller in ideal conditions, so extra shelter may be beneficial.
How to Plant
Plant rhizomes 5–10 cm deep with the eyes facing upward, ensuring they sit just below the soil surface. Space plants 50–70 cm apart to allow room for large clumps to expand. Water well after planting to settle the soil, apply a controlled-release fertiliser to support early growth, and mulch to conserve moisture and regulate soil temperature.
Pots and Containers
Canna Lilies thrive in large pots with good drainage. Use a high-quality potting mix enriched with compost. Position in full sun to partial shade, water consistently, and fertilise during the growing season for continuous flowers. In cooler climates, move pots into frost-free areas over winter and reduce watering to prevent rot.
Watering
Keep soil consistently moist during the growing season, but avoid waterlogging. Increase watering in dry spells and hot weather. In winter, reduce watering significantly and only water lightly if the soil becomes dry, especially where plants are dormant. Avoid allowing the soil to remain dry for extended periods. Always water at the base to keep foliage healthy and prevent fungal issues.
Fertilising
Apply a controlled-release fertiliser in spring, then top up with liquid or granular fertiliser throughout the season to support foliage growth and prolonged flowering. Plants in pots will benefit from more frequent feeding.
Mulching
Apply mulch around the base of plants in spring to regulate soil temperature, conserve moisture, and suppress weeds. Refresh mulch in autumn to help protect rhizomes from frost in cooler regions.
Maintenance
Deadhead spent flowers regularly to encourage new blooms and keep plants tidy. In warmer climates, once flowering has finished at the end of the season, cut away spent stems but retain healthy foliage, removing only leaves that are damaged or unsightly. In cooler or frost-prone regions, once frost arrives and the foliage dies back, cut plants to ground level in late autumn or after the first frost. In frost-prone areas, either cover with frost cloth or lift rhizomes for winter storage.
Division
Canna Lilies can remain undisturbed for many years, but clumps may eventually become crowded or flower less vigorously. To maintain strong growth, divide every three to four years in winter. Lift the clump, separate the rhizomes so each has at least one healthy shoot, and replant immediately. In cooler, frost-prone regions, divisions can be stored in a dry, frost-free place until spring.
Pests and Diseases
• Slugs and snails – common on young shoots; deter with barriers, traps, or baits
• Rust or bacterial blight – improve airflow, water at the soil level, and remove affected foliage
• General – monitor regularly and treat promptly to maintain plant health
Caution: Harmful if eaten.
