Garlic Mustard By Sarah Tse
This invasive species can be identified with the following description: Deeply growing, thin, white roots with stalky triangular heart-shaped leaves growing out of the stem. The flowers are button like with clusters of green pods dispersing seeds. Garlic Mustard is scented as horseradish. Garlic Mustard ranges in size to 30-100 cm. Garlic Mustard is self-fertilized or cross-pollinated.
This invasive species has taken away water sources for other native plants and has taken up habitat space because it is constantly growing. Garlic Mustard has allelochemicals which stimulates growth more rapidly. But due to this chemical, mycorrhiza fungi-that most plants use to to grow-is affected.

Most animals stay away from Garlic Mustard due to it’s overpowering taste so it is never consumed but scientist have still found ways to exterminate this plant. One way is burning, pulling or cutting the plant for small scale extermination but large scale extermination includes spraying chemicals to prevent it from dispersing seeds but this chemical also disrupts other native plants. One way commonly used is replanting small trees around it, so it prevents in from gaining any sunlight.
