Perilla

This herb-ey salad green is another edible plant that is messing with native plants throughout the U.S. Perilla is originally from Asia, and like other invasive species, the entire root system has to be pulled out of the ground to ensure that it won’t grow back. Perilla is also known as beefsteak and can poison cattle. It is found throughout the country because its seeds are spread with the wind.
You’ll especially find it in Korean dishes, where the leaves will be marinated and served as a side. Beefsteak plants make a great addition to a lot of meals (unless you’re a cow). It’s actually sold in some supermarkets under other names like wild basil. But why pay money for these leaves that may be growing near you?
