Garlic mustard (Alliaria petiolate) belongs to the Brassicaceae (the Mustard family). It is a biennial herb that is native to Europe, western and central Asia, and northwestern Africa. This herb grows along the margins of hedges, and it can reach 30-100 cm in height. The leaves are stalked, triangular to heart-shaped, when crushed smell like garlic. The white flowers bloom in button-like clusters in spring and summer. Each small flower has four white petals, and arranged in a cross shape. The fruits are erect, slender, four-sided pods 4 to 5.5 cm long. In 17th century Britain it was recommended as a flavoring for salt fish. It can also be made into a sauce for eating with roast lamb or salad.
