Description
Phragmites, also known as common reed, is a tall grass that can grow up to 20 feet tall. It is native to wetlands and is commonly found in North America, Europe, and Asia. While it has been used for thatching roofs, making baskets, and as a food source for livestock, it is often considered as an invasive species due to its tendency to spread rapidly and outcompete native plants.
