Garlic mustard, Alliaria petiolata, grows in shaded areas along hedgerows and the edges of woods, roadsides and parks. It is found throughout Europe as well as large parts of the US and Canada.

All parts of the plant are edible, the flowers can be cooked like broccoli, the roots have a horseradish like taste and unsurprisingly the leaves have a garlic mustard flavour. For best use the leaves should be picked in the plants first year and before the plant flowers.
Leaves are heart shaped wit toothed prominent edges and can be used in salads, pesto or to flavour soups.
