Common Reed, scientifically known as Phragmites australis, 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 and fall. This plant plays a crucial role in its ecosystem by providing habitat for various wildlife and helping to stabilize soil. Common Reed is known for its ability to thrive in diverse environments, including both freshwater and brackish water. It can spread rapidly through rhizomes, which are underground stems, making it a dominant species in many areas. While it offers ecological benefits, its aggressive growth can sometimes lead to the displacement of native plants.
