Invasive (Phragmites australis subsp. australis) and native species can live closeby each other, making their identification difficult.


Invasive Phragmites

  • Grows densely with as many as 200 stems per square metre
  • Up to 5 metres tall
  • Has stems that are tan or beige in colour with blue-green leaves and large, dense seedheads.

Native Phragmites

  • Usually not as dense as the invasive plant
  • Well-established stands are frequently mixed with other plants
  • Usually has more reddish-brown stems, yellow-green leaves and smaller, sparser seedheads
