Jack-in-the-hedge (Alliaria petiolata) is also known as garlic mustard. The chopped leaves and flowers and seeds can be used for flavoring salads and sauces with a mild flavour of both garlic and mustard.
Archaeological remains in the Baltic indicate that garlic mustard has been used in cooking in Europe for over 8000 years. Garlic mustard also has disinfectant or diuretic properties.
It has escaped from the hedge to the clearing in the wood and is being munched by a happy colony of brassica bugs.
