Cornflower ‘Black Ball’ is a striking twist on the classic blue cornflower. Its deep, rich crimson—almost black—blooms bring a moody elegance to the cutting patch or border. The flowers are full and velvety, and work beautifully alongside paler tones like Ammi, Cosmos, or Calendula for contrast.
A hardy annual, ‘Black Ball’ is easy to grow and thrives in poor soil with plenty of sun. It’s a great choice for new gardeners or anyone looking to fill space with reliable colour. The more you cut, the more it flowers—perfect for keeping the vases full and the bees buzzing.
Sow seeds direct in autumn for earlier blooms, or in spring (March to May) for summer flowers. Thin seedlings to around 20cm apart and enjoy the show.
Height: 80–90cm Seeds per packet: approx. 200 Hardy annual
An old-fashioned favourite with a dramatic twist—elegant, productive, and a touch on the gothic side.
