Overview

A spectacular tropical perennial perfectly suited to Adelaide's warm summer climate, Canna 'Tropicanna' delivers bold year-round foliage drama with large paddle-shaped leaves striped in vibrant burgundy, pink, orange, yellow and green.

Fast-growing, heat-loving and creating instant tropical impact, it thrives in hot, sunny positions with regular summer water. Ideal for tropical-style gardens, poolside plantings, bold borders, large containers and feature positions, 'Tropicanna' brings explosive colour and lush exotic elegance to water-loving South Australian landscapes.

Key Features

• Mature Size: 1.5–2.0 m H × 0.6–1.0 m W (clumping habit)
• Growth Rate: 50–80 cm per year under good conditions (fast growth in warm weather)
• Foliage: Large, bold paddle-shaped leaves spectacularly striped in burgundy, pink, orange, yellow and green; tropical appearance; dies back in winter (herbaceous—emerges from rhizomes in spring)
• Flowers: Brilliant orange tubular flowers on tall stems above foliage; blooms summer through autumn (December–April)
• Fragrance: Not fragrant
• Seasonal Interest: Spectacular multi-coloured foliage spring through autumn; vibrant orange summer–autumn flowering; dies back to ground in winter (dormant rhizomes underground)
• Wildlife Value: Flowers attract hummingbirds (not present in Australia), bees, and butterflies
• Tolerance: Moderate drought tolerance once established (performs best with consistent moisture); exceptional heat tolerance; frost-tender (rhizomes may survive light frosts underground but foliage dies back; protect from hard frosts or lift and store rhizomes in cold areas); wind-tolerant in sheltered positions; prefers consistent moisture during active growth
• Planting Density: Border/mass planting: 2–3 plants per m²; Feature/specimen: 1 plant per focal point or large container
• Pet Friendly: Use caution—all parts are toxic if ingested by pets or humans; can cause vomiting, diarrhea, and other symptoms; generally not palatable but discourage chewing

Where It Works Best

• Sunlight: Full sun (essential for best foliage colour and flowering; tolerates light afternoon shade but colours may fade)
• Soil: Well-drained, moisture-retentive loam enriched with organic matter; thrives in fertile, humus-rich soils; excellent in large containers with premium potting mix; tolerates Adelaide's alkaline soils if amended with compost
• Water Needs:
  • Establishment: Deep soak 2–3 times weekly for 8–12 weeks
  • Established: Deep soak 2–3 times weekly in summer for best foliage and flowering (water-loving during active growth); reduce watering as foliage dies back in autumn; minimal to no watering in winter dormancy
• Maintenance: Moderate maintenance; remove spent flower stems to maintain tidiness; cut back dead foliage to ground level in late autumn–winter after it dies back; divide congested clumps every 3–4 years in spring to maintain vigour and increase stock; feed regularly during growing season (early spring through autumn) with balanced fertiliser or compost; mulch heavily to retain moisture and suppress weeds; in cold-winter areas, lift and store rhizomes indoors over winter
• Lifespan: 10–20+ years with periodic division (rhizomes are long-lived)
• Climate Zones: Ideal for Mediterranean and temperate South Australia—Adelaide plains, foothills, Fleurieu Peninsula, warm inland gardens; performs best in warm, frost-free or light-frost areas
• Soil pH: Slightly acidic to neutral (pH 6.0–7.0); tolerates mildly alkaline soils if enriched with organic matter
