Garlic Mustard Overview

Alliaria petiolata is a biennial herbaceous plant from the Brassicaceae family. It is found growing naturally throughout much of Europe and commonly known by many names. Some common names for this plant are Garlic Mustard and Jack By The Hedge. Garlic Mustard is hairy and can reach a range of heights, it doesn't typically branch and the leaves are heart to kidney-shaped. The foliage has a strong garlic scent, hence the common name Garlic Mustard. Flowers are white in colour and measure between 3-5mm across. Leading onto long seed capsules. This species is part of the Royal Horticultural Society “Plants for Pollinators” initiative to showcase plants which support pollinator populations by providing ample amounts of nectar and/ or pollen. A great choice for encouraging pollinating insect wildlife into your garden!

Other uses of Garlic Mustard

Wildflower/meadow culinary. Both flowers and leaves can be eaten raw in salads and have a slightly bitter mustard-garlic taste that works well when blended with blander-tasting leaves. Ecologically, in Europe it is an important food plant for butterflies, moths and weevils. In North America it is invasive and has reduced biodiversity in the under-story of woodland and in flood plain areas.
