Garlic Mustard – Alliaria petiolata

Also called Jack-By-The-Hedge and Hedge Garlic, appearing in early spring, a hairy plant with multitudes of small white flowers with four petals. The leaves are large and triangular, and when crushed gives off a smell of garlic. The whole plant is known for its medicinal properties, as well as for flavouring foods. It grows to a height of between 40-120 cm.

It flowers April to June, and can be seen on woodland margins, roadside verges, banks, waste ground, and in hedgerows. Common and widespread throughout most of Britain, though scarce in northern Scotland.

Garlic Mustard is a foodplant for the Orange-tip butterfly. The caterpillars feed on the elongate seedpods. It is also an important food source for other butterflies as well as moth larvae, and other insects.
