Characteristics

• Foliage : Arrow-shaped, rich green leaves speckled with decorative white spots. Deciduous in Canada (must be overwintered indoors).
• Flowers : Large, funnel-shaped blooms of intense, uniform purple-pink, held on sturdy, upright stems.
• Light Requirements : Prefers full sun for optimal colour intensity but tolerates partial shade, especially during sweltering afternoon heat.
• Habit : Upright, compact, and architectural.
• Growth : Moderate growth rate, reaching approximately 45 to 60 cm in height.
• Soil : Requires a rich, fertile, and exceptionally well-drained substrate to prevent rhizome rot.
• Temperature : Canadian hardiness zone 9 (treated as an annual or tender bulb in Quebec).
• Resistance : Good resistance to fungal diseases when drainage is adequate; rarely affected by common pests.

Utilization

• Types of Use : Ideal for containers on a terrace, as a border plant in garden beds, or as a high-end cut flower for premium bouquets.
• Decorative Advantages : Provides strong vertical structure and exceptional colour depth; the mottled foliage remains decorative even when the plant is not in bloom.

Maintenance

• Watering : Keep the soil consistently moist during the active growing season, but avoid waterlogging the medium.
• Fertilization : Apply a balanced flower fertilizer every two weeks from June to August to support continuous blooming.
• Pruning : Remove spent blooms by cutting the stem at the base to encourage the development of new buds.
• Planting : Plant rhizomes 10 cm deep once all risk of frost has passed and the soil has warmed up.
• Winter Protection : Dig up rhizomes after the first light frost, allow them to dry, and store in a cool, dry place (around 10°C) for the winter.
