Canna 'Tropicanna Black Knight' – Black Canna Lily | Dramatic Tropical Foliage and Brilliant Scarlet Flowers

Canna 'Tropicanna Black Knight' is a spectacular ornamental canna lily grown for its exceptionally dark foliage and vibrant red flowers. This modern canna cultivar combines the bold architectural presence of traditional Cannas with some of the darkest foliage available in the genus, creating a dramatic tropical effect in gardens, terraces and large containers.

What makes Canna 'Tropicanna Black Knight' particularly special is the contrast between its rich, near-black leaves and its luminous scarlet-red flowers. As the season progresses, the foliage develops increasingly intense shades of deep burgundy, plum and black, creating visual interest long before the first flowers appear. When backlit by morning or evening sunlight, the foliage can be breathtaking, revealing subtle red and purple undertones that many photographs fail to capture fully.

At TOMs FLOWer CLUB, we consider this one of the finest foliage Cannas available today. It offers months of ornamental value, combining exotic appearance, vigorous growth and relatively easy cultivation. Whether used as a specimen plant, tropical border accent or container feature, Canna 'Tropicanna Black Knight' brings a genuine jungle-like atmosphere to any planting scheme.

Collector Note

Collectors of tropical and architectural plants often seek out foliage that remains ornamental throughout the growing season. While many Cannas are primarily grown for their flowers, Canna 'Tropicanna Black Knight' is equally admired for its foliage.

Its almost black leaves create dramatic contrasts within mixed plantings and pair beautifully with silver, lime-green or brightly coloured foliage plants. Among dark-foliaged Cannas, 'Tropicanna Black Knight' is widely appreciated for the richness of its colouration and the intensity of its red flowers.

For collectors creating exotic, jungle-inspired displays, this cultivar is frequently considered an essential feature plant.

Care

Light: Full sun is ideal. The darkest foliage colours and strongest flowering occur in bright, sunny positions.

Watering: Water regularly during active growth. Keep evenly moist but avoid prolonged waterlogging.

Humidity: Average outdoor humidity is sufficient.

Temperature: Prefers warm growing conditions. Not frost tolerant.

Substrate: Rich, fertile and well-draining soil or container substrate.

Maintenance: Remove spent flower stems if desired. Feed regularly during active growth for maximum performance.

Additional cultivation tips:

• Plant in a sheltered, sunny location for best results.
• Cannas respond well to regular organic feeding throughout summer.
• Large containers produce excellent specimen plants.
• Rhizomes can be lifted in autumn before frost.
• Store dormant rhizomes frost-free in barely moist compost over winter.
• Replant outdoors after the danger of frost has passed in spring.

Cultivated with Care at TOMs FLOWer CLUB

At TOMs FLOWer CLUB, our Cannas are cultivated according to the principle of quality before quantity. Rather than pushing rapid growth through excessive fertilisation, we focus on producing healthy, balanced plants with strong root systems and long-term vitality.

Each plant is grown in our self-mixed permeable organic substrate, providing excellent drainage while maintaining adequate moisture and nutrition. Our plants are not over-fertilised and are grown without intensive mass-production methods.

This slower cultivation approach creates robust specimens that establish quickly and continue performing strongly throughout the growing season.
