Why We Love It:

Wild Cornflower (Centaurea cyanus) is a nostalgic, cottage garden favourite with vivid blue blooms that attract bees, butterflies, and other pollinators in abundance. Its tall, airy stems make it perfect for naturalistic planting schemes and fresh summer bouquets. Easy to grow with minimal fuss, it brings a romantic touch of the countryside into even the smallest urban garden.

Planting & Care Tips:

• 
  
  When to Plant: Sow outdoors March–May or in autumn (September–October) for earlier blooms


• 
  
  Where to Plant: Open, sunny site directly into prepared soil or containers


• 
  
  Spacing: Thin seedlings to approx. 15–20cm apart


• 
  
  Care Notes: Water regularly during dry spells and deadhead faded flowers to prolong blooming

The Nunhead Gardener Recommends:

Plant alongside poppies and oxeye daisies for a classic wildflower meadow feel. Great in borders, but also thrives in large pots—perfect for brightening up balconies and roof terraces in South London.
