Cornflower - Centaurea cyanus 'Black Boy'

Centaurea Cyanus or Cornflower

Not your classic bright blue cornflower but now in a very pretty dark color.
As a hardy annual, cornflowers benefit greatly from sow sheltered in a cold greenhouse in autumn. This way you have taller, sturdier plants in the spring. But you can also sow it in the spring.

Feel free to keep cutting this plant, so you will always have new stems. The bees love this too.

Type: hardy annual
Location: Full sun
Height: 75 cm to 140 cm (for autumn sowing)
