Parrot Feather emergent pond plant

Myriophyllum aquaticum is a rooted aquatic plant. It produces branching stems that are brownish red to green. Parrotfeather gets its name from the feathery bright green leaves that grow from the stems. Although this is a submerged plant, parts of the plant can grow up to 12 inches out of water.

Parrotfeather and eurasian watermilfoil are often misidentified as one another. Both are members of the same plant family. Eurasian watermilfoil grows only below the water surface, whereas the parrot feather produces emergent stems.
