Hedge garlic is an herbaceous biennial plant, meaning it has a two-year life cycle. In the first year, it forms a compact basal rosette of heart-shaped leaves with rough teeth. During year two, Garlic Mustard develops a flower stalk and reaches up to 120cm tall. The seed pods are green and thin.

Garlic Mustard lookalikes

It could be confused with Honesty (Lunaria annua) by the leaves, but it has purple flowers. Garlic Mustard also resembles Yellow Archangel (Lamium galeobdolon), however flowers are yellow and leaves are often variegated. None of those two smell of garlic, like it does Hedge Garlic.

All about Garlic Mustard

This biennial herb, member of the cabbage family, does exactly what it says on the tin. The flavour is a pleasant mixture of mild garlic and a hint of mustard, though it becomes bitter after flowering.

You’ll find it growing abundantly in the shade of hedgerows and woodland edges, along footpaths and disturbed areas all year long, though it’s best picked early to mid-spring.

How to identify Garlic Mustard

Garlic Mustard has been little used in herbal medicine. The leaves are effective in relieving the itching caused by bites and stings and have been used to treat asthma, bronchitis and eczema.

Culinary uses and recipes with Garlic Mustard

Every part of the plant is edible. The flowers make a pretty garnish for salads and the dried seeds work as a poor man’s mustard. The long thin taproot has a mild horseradish flavour too.

The leaves are best finely chopped and added sparingly to salads or eaten in cheese sandwiches. A “pesto” sauce seems to be a forager’s favourite, but it also pairs very well with lamb. Add to soups and stews at the very end of cooking, otherwise they’ll make the meal taste bitter.
