History, uses and notes:

Once considered a weed that grew around fields of corn, it was almost eradicated by industrial agriculture techniques. 

Making a small comeback as an ornamental flower in private gardens, the cornflower may be saved by its inherent beauty. 

Similarly to Common Knapweed, they are part of the Centaurea genus which are highly popular with bees due to their high nectar levels.

As an annual in your garden, the Cornflower will flower within the first year, depending on when it's sown.

Description:

The outer florets are star-like, and smaller, more purplish flowers are found in the middle. Stems and leaves are long and pointy, with hairy, blackish buds at the tips.
