Corncockle (Agrostemma githago - also Corn cockle and Corn-cockle) is a slender pink flower of European corn fields. In the 19th century, it was reported as a very common weed of wheat fields and its seeds were inadvertently included in harvested wheat seed and then re-sown the following season. It is very likely that until the 20th century, most wheat contained some corncockle seed. It is now present in many parts of the temperate world as an alien species, probably introduced with imported European wheat. It is known to occur throughout much of the USA and parts of Canada, parts of Australia and New Zealand. In parts of Europe such as the UK, intensive mechanised farming has put the plant at risk and it is now uncommon or local. This is partly due to increased use of herbicides but probably much more to do with changing patterns of agriculture with most wheat now sown in the autumn as winter wheat and then harvested before any corncockle would have flowered or set seed. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

It is a stiffly erect plant up to 1 metre tall and covered with fine hairs. Its few branches are each tipped with a single deep pink to purple flower. The flowers are scentless, are 25 mm to 50 mm across and are produced in the summer months - May to September in the northern hemisphere, November to March in the southern hemisphere. Each petal bears 2 or 3 discontinous black lines. The five narrow pointed sepals exceed the petals and are joined at the base to form a rigid tube with 10 ribs. Leaves are pale green, opposite, narrowly lanceolate, held nearly erect against stem and are 45 mm to 145 mm long. Seeds are produced in a many-seeded capsule. All parts of the plant are reported to be poisonous. The metre (Commonwealth English) or meter (American English) (symbol: m) is the SI base unit of length. ...
