Cornflower Centaurea cyanus

"And for the blue that o’er the sea is born, A brighter rises in our standing corn."

- Anne Finch, "An Invitation to Daphnis" 

Description

Where it grows

Cornfields, roadsides and hedgerows, particularly on light and sandy soils.

Best time to see

Flowers from June to August.

Cultural info

How's it doing?

The cornflower owes its decline to modern agricultural practices, such as increased use of herbicides and fertilisers, the development of highly competitive crop varieties, the destruction of field-edges, the demise of traditional crop rotations and the conversion of marginal arable land to pasture. These factors continue to be a threat to its future. The decline of the cornflower illustrates what has happened to many of our wildflowers over the last 60 years.
