Yellow Nutsedge

The yellow nutsedge (Cyperus esculentus), is a perennial herb that's native to the southern United States. It has the ability to survive in all kinds of soils due to its tuberous roots that store energy. In fact, certain parts of the tuberous roots called "esculentus" are edible and are sometimes called the "Earth almond." Once the plant's roots are removed from the soil, the tubers can be eaten raw or cooked. They have a nutty taste that can be made into beverages, olive oil, or a coffee substitute.
