Common Reed | Phragmites australis
Commonly called Phragmites [frag-mite-eez], this invasive emergent plant can form large colonies that dominate the ecosystem. The stems are round and can grow over 15 feet tall. The leaves are flat, one to two inches wide, and grow in an alternating pattern up the stem. The head of these plants resembles a feathery plume with many tiny seeds.
