Corn gromwell (Buglossoides arvensis) is an ancient introduction and field weed in Finland, which was also used as a colouring plant. Plant books maintained a misconception about its commonness until it was noticed that it had declined drastically due to improvements in weed seed filtering. Could it make a return to organically grown autumn cereal fields?
