Garlic Mustard Overview

Alliaria is a small genus of herbaceous biennial flowering plants in the mustard family of Brassicaceae with only 3 accepted species. This genus is characterised by the strong odour given off by all parts of the plant. Commonly known as garlic mustard, the species Alliaria petiolata smells like garlic when physically disturbed. Clusters of button-like white flowers are produced, which lead on to hundreds of shiny black seeds which can be dispersed multiple metres from the parent. Hence why this species can colonise entire areas easily through self-fertilisation.
