Corncockle Overview

Agrostemma is a small genus containing just 2 annual species, commonly called Corncockles. These plants range from southeastern Europe to western Asia. Corncockles produce oppositely arranged leaves and solitary flowers with 5 petals. The flowers are trumpet-shaped and usually pink, red or white, with discrete striped markings on the inner petals. All parts of these plants are toxic and they are considered weeds in many locations.

How to propagate Corncockle


By seed sown in spring or early autumn.
