All you need to know about Garlic Mustard

How to identify

Garlic Mustard resembles several native Ontario plants. The leaves at the base of the plant look like those of several plants in the carrot family, daisy family and the violet family. The seed pods look like those of several other mustard species. The easiest way to distinguish Garlic Mustard from these other plant families is to crush the leaves. If they emit a strong garlic smell, then the plant is most likely to be Garlic Mustard.


Garlic Mustard can invade relatively undisturbed forests. Once established it can displace native wild flowers like trillium and trout-lily. It hinders other plants interfering with the growth of fungi that bring nutrients to the roots of the plants. The plant threatens several of Ontario's species at risk, including American Ginseng, Drooping Trillium, False rue-anemone and many more.
