Agrostemma githago, a cornfield annual, the common corn-cockle (also written “corncockle” and “corn cockle” and known locally simply as “the corncockle”), is a slender pink flower of European wheat 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 resown the following season. It is very likely that until the 20th century, most wheat contained some corncockle seed.
