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. While Phragmites australis is native to many regions, it can become invasive in some areas, outcompeting local vegetation. Its rapid growth and ability to thrive in disturbed environments can lead to reduced biodiversity, making management efforts important in affected ecosystems.
