  • Flowers : Displays intense cobalt blue double flowers, clustered in tight spikes for maximum visual impact.
  • Light : Requires a full sun location to maintain the rich flower colour and sturdy habit.
  • Habit : Upright, proud, and naturally short, eliminating any need for staking even during inclement weather.
  • Growth : Shows a moderate growth rate, ensuring a balanced and dense silhouette.
  • Soil : Prefers fertile soil, rich in organic matter and providing excellent drainage.
  • Temperature : Exhibits exceptional hardiness, adapting perfectly to the harsh winters of Zone 3.
  • Resistances : Shows increased resilience to wind and leaf diseases thanks to its stocky structure.

Utilization

  • Types of use : Integrates beautifully into perennial mass plantings, structured borders, or in containers on a sunny balcony.
  • Decorative benefits : Brings an unparalleled depth of blue; perfect for adding verticality and drama to small spaces.

Maintenance

  • Watering : Provide regular watering to keep the soil cool, especially in dry weather, while avoiding standing water.
  • Fertilization : Apply a phosphorus-rich granular fertilizer at the first sign of spring growth to support blooming.
  • Pruning : Cut back flower stems as soon as they fade to encourage a second flush of flowers later in the season.
  • Planting : Space plants adequately to promote air circulation and plant in amended soil.
  • Winter Protection : Cover the base with a layer of mulch in the fall to protect the root system.
