Blue Cornflowers

Cornflower, also known as bluebottle, is a tall, slender, annual plant with long and fine, grey-green leaves. In the summer it grows bright blue flowers, but occasionally they can be white, pink, or purple. It is often found in cornfields and waste ground in Europe and western Asia.

The flower is part of the genus Centaurea (also known as knapweed) which name comes from the legendary centaur Chiron, famed for his knowledge of herbs.
