Phragmites australis, commonly known as common reed, is a tall, perennial grass that typically grows in wetlands, marshes, and along riverbanks. It can reach heights of up to 15 feet and has feathery flower heads that appear in late summer. This plant plays a crucial role in its ecosystem by providing habitat for wildlife and helping to stabilize soil. Common reed is known for its ability to thrive in various conditions, including both freshwater and saltwater environments. While it is native to many regions around the world, it can become invasive in some areas, outcompeting native plants and altering local ecosystems.
