Agrostemma or more commonly known as cockle, corn cockle, corncockles, slender corncockle are summer flowering annuals. Best grown in full sun; flowers best in very well drained soil that is not very fertile. Support with sticks and deadhead to prolong flowering. Its best-known member is A. githago syn A. gracilis, the common corncockle, which is a native of Europe that has naturalized in most of the USA. Depending on the species, the flowers are usually saucer shaped, 1-1.5 inches (3-4cm) and have 5 pink to purple petals that bloom all summer. Unfortunately the plant is becoming rarer due to modern farming practices. Self seeds.
