Photographs of Myriophyllum aquaticum

Views of an oxygenating plant commonly called water milfoil, diamond milfoil, or parrot's feather growing in nursery containers and ponds. This plant species—Myriophyllum aquaticum (Vell.) Verdt., Myriophyllum brasiliense Camb., or Myriophyllum proserpinacoides Gillies ex Hook. & Arn.—is highly invasive and should be planted in self-contained ecosystems (preferably in tanks or other types of containers) so as to prevent it from contaminating the local natural ecosystems. This plant species can be used in constructed wetlands for wastewater treatment. (Photographs by Jo-Shing Yang)
