Parrot Feather
Myriophyllum aquaticum

A feathery leaved, perennial aquatic plant with stems that grow up to 2m in length. The tips of the stems frequently protrude up to 30cm from the water. Seeds that are produced in Australia are infertile as only female plants are recorded here.



  • Parrot feather reproduces by fragments of stem breaking from the parent plant and is moved by water currents.
  • Once also commonly found in home aquaria as the plant was once sold as an attractive fish tank plant. Inappropriate disposal of aquatic plants leads to choking of waterways, excluding all native flora and fauna.
