Plant Profile: Corncockle (Agrostemma githago)

Agrostemma githagoCorncockle is an upright annual belonging to the carnation family (Caryophyllaceae) and is a native of Europe where it grows in disturbed sites such as fields and roadsides. It was considered a weed of wheat fields until the twentieth century when agricultural practices changed and is now cultivated as an ornamental. The grey-green leaves are narrowly lanceolate and are carried upright close to the stem. The five petalled flowers are trumpet shaped, magenta with black striping, and about one to two inches across. In summer they are borne singly on stiff stems that sway gently in the breeze and are subtended by narrow sepals that are longer than the petals. Plants readily self-sow. An excellent choice for a cottage garden and good cut flower.
