Species of the Week- Garlic Mustard
Garlic Mustard, also known as Alliaria petiolata, can be found in the herbaceous layer of Charles river wetlands, the Sachar Woods, and in just about every nook and cranny around campus. This invasive plant spreads quickly through wind spread seeds and sprouts early in the spring. Garlic mustard is also allelopathic, meaning it excretes chemicals that limit the growth of other species of plant and soil enriching ribosomal fungi. With no native herbivores to keep it in check, the fast spreading and fast growing garlic mustard can easily outcompete native herbaceous plants and take over New England forests.

Originally found in Europe and Western/Central Asia, this edible plant was brought to North America by European colonists for its use as a spice. The round, heart-shaped leaves can be cut and ground up to be included in a pesto. When collecting, it is better to pick younger leaves, as second year garlic mustard plants are more bitter. Happy harvesting!
