Eurasian watermilfoil is an exotic species. Its leaves are feather-like and sometimes produce reddish flowers that extend above the water. The stems are red to brown in color. It can dominate a pond very quickly by fragmentation. Pieces of the plant grow roots to develop a new plant. There are many native milfoil plants which do not have as many feather-like leaves and are much less aggressive.
