Uniquely identifiable characteristics: There is no other plant quite like this one.

Distinguishing Feature : The leaves smell of garlic when crushed.

Garlic Mustard smells of garlic when the leaves are crushed. It is edible; the seed containing pods can be fried, or the seeds crushed as a condiment. The leaves can be added to savoury dishes, or eaten raw on sandwiches.

In some parts of the World, Garlic Mustard is regarded as an un-wanted and invasive species.

The leaves yield a yellow dye.

This plant likes to inhabit hedgerows, hence the name 'Jack by the Hedge', and dislikes being in the sun all day. It is one of the most common spring-time flowers, almost ubiquitous throughout the UK, apart from northern Scotland where it is absent. Stands to a height of up to 1 metre.
