Characteristics
Foliage : Lance-shaped, deeply textured dark green leaves form a tidy, dense basal clump that hugs the ground.
Flowering / Fruit / Stems : Long, sharply pointed flower spikes tightly packed with small, lavender-purple blossoms that open progressively from the bottom upward.
Light : Requires full sun to maintain structural stem rigidity and achieve peak flower coloration.
Habit : Erect, columnar, and compact, holding its proud silhouette firmly without flopping.
Growth : Displays a moderate growth rate, reaching a height of 75 cm and a spread of up to 60 cm.
Soil : Thrives in loose, fertile, and sharply drained soil. Avoid waterlogged soils, especially during winter.
Temperature : Exhibits exceptional winter hardiness, comfortably surviving down to zone 3.
Resistances : Stands up well to transient summer drought once established and strongly deters white-tailed deer, hares, and rabbits, while showing high resistance to powdery mildew.
Use
Types of use : Structures the middle or back of sunny borders, anchors contemporary mass plantings, embellishes rock gardens, or performs beautifully as a focal point in a patio container.
Decorative benefits : Provides a powerful vertical accent that punctuates the monotony of mounded or rounded plants. The blossoms make long-lasting, elegant cut flowers for fresh arrangements.
Maintenance
Watering : Water regularly during the first growing season to establish a deep root system. Once established, maintain a moderate watering schedule and allow the soil surface to dry slightly between applications.
Fertilization : Spread a layer of compost in early spring or apply a balanced, slow-release granular fertilizer as new growth emerges.
Pruning : Cut back spent flower spikes promptly to encourage continuous secondary blooms. Shear the entire plant down to ground level in late autumn or early spring.
Plantation : Space plants 45 to 60 cm apart to ensure excellent air circulation and prevent fungal issues.
Winter Protection : Avoid planting in low-lying areas where water accumulates during the cold season. Leave the healthy crown uncovered, as this extremely hardy plant naturally survives freezing temperatures without any artificial winter protection.
