Why We Love It:

Cornflower ‘Double Blue’ produces masses of stunning, rich blue, frilly blooms that add height, movement, and vibrancy to any garden setting. These hardy annuals are adored by pollinators and are equally fantastic for fresh or dried flower arrangements. Easy-going and quick to flower, they’re a wonderful addition to wildflower mixes, cottage gardens, and bright borders.

  When to Plant: Sow outdoors from March to May or in late summer for earlier flowers next year


• 
  
  Where to Plant: Directly into a sunny, sheltered spot in beds or large containers


•

• 
  
  Care Notes: Water during dry spells, thin seedlings if overcrowded, and deadhead spent blooms to encourage continuous flowering

The Nunhead Gardener Recommends:

Perfect paired with poppies, cosmos, and nigella for a classic wildflower look. Try sowing a patch near your vegetable garden to attract pollinators and beneficial insects.
