Common Reed
Grass, 6-13’ in height. History of introduction unclear.

  • Tall grass with plume-like flowers.
  • Leaves are gray-green in color.
  • Dry flower stems remain standing throughout winter.
  • There is also a rare, native genotype.
Know how to separate the two before eradicating!
The Problem:
Spreads rapidly, especially in floodplains and wetlands where it forms huge stands, excluding other plants. Releases chemicals toxic to other plants thereby preventing their establishment (allelopathic).
