Bring an explosion of tropical colours and unique dynamism to your garden with Canna 'Pretoria'. This variety is a true visual spectacle, distinguished by its green foliage striped with bright yellow, evoking tiger stripes, hence its nickname. Topped with vibrant orange flower spikes, Canna 'Pretoria' is an imposing plant that ensures a striking impact and an exotic ambiance throughout the summer season.

Characteristics

• Foliage : The most distinctive feature of Canna 'Pretoria' is its foliage. The large, paddle-shaped leaves are a medium green with bright lemon-yellow horizontal and vertical stripes, creating a very striking striped pattern. The foliage is deciduous in cold climates.
• Bloom : Produces single, pure and vibrant orange flower spikes. Blooming is abundant and continuous from mid-summer until the first autumn frosts, standing out beautifully against the striped foliage.
• Light : Prefers full sun for optimal growth and the most vibrant colours. Requires at least 6 hours of direct sunlight per day.
• Habit : Its habit is upright and imposing, forming a vertical clump of large leafy stems topped with flower spikes.
• Growth : It's a fast-growing plant, capable of quickly reaching its mature size and creating a significant impact in the garden.
• Humidity : Likes consistently moist, but well-drained soil. Does not like prolonged dry conditions, especially during peak bloom.
• Soil : Prefers rich organic matter, fertile, and well-drained soil. Heavy, clay soil should be amended.
• Temperature : Being a tropical plant, Canna is not frost-hardy. In cold climates, rhizomes must be dug up and overwintered indoors.
• Watering : Requires regular and abundant watering, especially during hot and dry periods, and if grown in containers. Soil should be kept moist.

Uses

• Types of Use : Ideal as a central element or "thriller" in mass plantings, tropical flower beds, large patio containers, or at the edge of water features. It's perfect for adding height, structure, and an exotic ambiance to any landscape.
• Decorative Advantages : Its unique striped foliage and vibrant orange flowers create a striking visual contrast that immediately draws the eye. It brings a dramatic and tropical touch that lasts all summer.

Care

• Fertilization : Fertilize regularly during the growing season (spring to late summer) with a balanced fertilizer for flowering and foliage plants, to support its fast growth and abundant blooming.
• Pruning : To encourage continuous blooming, remove spent flowers after they have completed their cycle. In the fall, after the first frost turns the foliage black, cut stems back to about 10-15 cm (4-6 inches) from the ground before digging up the rhizomes for overwintering.
• Planting :
  • Distance : Plant rhizomes approximately 45 to 60 cm (18 to 24 inches) apart to allow for their spread and optimal development.
  • Depth : Plant rhizomes horizontally, about 10 to 15 cm (4 to 6 inches) deep, with the "eyes" (buds) facing upwards.
  • Period : Plant outdoors in spring, after all risk of frost and when the soil is well warmed. Rhizomes can be started indoors 4 to 6 weeks before the last frost for earlier blooming.
