Type: Hardy perennial
Best Grown: Borders, cottage gardens, pollinator-friendly planting
Sowing Time: February–June or September–October (can benefit from cold stratification)
Flowering Time: June–August
Spacing: 30–45 cm apart
Height: 90–150 cm tall
Difficulty: Moderate (slow to germinate)

Why grow it?

• Tall, architectural flower spikes in deep blue-violet shades
• Excellent cut flower (handle with gloves)
• Thrives in cooler climates
• Long-lived once established
• Pollinator-friendly in summer

How to grow: Sow indoors February–June, or in autumn for natural winter chilling. Seeds often need a period of cold to germinate — either sow outside in a sheltered seedbed or stratify in the fridge for 3–6 weeks before sowing. Transplant seedlings to their final position in rich, moist but well-drained soil. Prefers partial shade but tolerates full sun in cooler areas.

Usage ideas: Ideal for the back of borders, cottage gardens, or pollinator planting schemes. Pairs beautifully with delphiniums, lupins, and foxgloves.

⚠ Caution: All parts of the plant are poisonous. Wear gloves when handling and keep away from children and pets.
