    The cornflower, Bachelor's Button, is a native of Europe and widely cultivated in North America, so much so that it has escaped from gardens and naturalized. It is an annual herb, with an erect wiry stem that branches and can grow to about 2 feet tall. At the ends of the branches grow single brilliant blue flowerheads. It has long grayish green leaves that are lance shaped and downy like the stem.

    At one time it was considered a medicinal plant, and it does have the qualities of an astringent.
