How to Grow Cupid's Dart
Catananche caerulea
Cupid's Dart is a drought-tolerant Mediterranean perennial with papery blue-lavender flowers from June to August. Plant in full sun and very well-drained, poor soil — it hates winter wet. Space 30 cm apart. Deadhead regularly for continuous blooms. Short-lived (3-4 years) so divide every 2-3 years or take root cuttings in winter. Excellent for cutting and drying. Virtually pest-free in the right conditions.
Yearly Lifecycle
Care Essentials

☀️ Light
Full sun essential
Requires full sun for best flowering. At least 6 hours of direct sunlight daily. Will not thrive in shade or partial shade.
💧 Watering
Low water needs; drought-tolerant once established
Water sparingly once established. Prefers dry conditions. Overwatering and wet soil, especially in winter, will kill the plant faster than drought.
🌱 Fertilizing
Minimal feeding; lean soil preferred
A light application of general-purpose fertiliser in spring is sufficient. Rich soil produces lush foliage at the expense of flowers. Do not mulch with organic matter.
Growing Tips
Drainage is everything
Cupid's Dart dies from winter wet, not cold. Plant in gravel gardens, raised beds, or add grit to heavy soil. A gravel mulch around the crown is better than organic mulch.
Deadhead for months of bloom
Remove spent flower stems as they fade to encourage a second and third flush. Left alone, flowering stops after the first wave.
Plan for succession
Plants are short-lived (3-4 years). Take root cuttings in winter or divide in spring every 2-3 years so you always have young, vigorous plants coming through.
