Northern Milfoil is a native plant that grows in depths of up to 20 feet. Dark Green feathery leaves are grouped in fours around a hollow stem that is usually pinkish in color. Will raise a 3-4 inch reddish flowering spike above the surface.
Often mistaken for coontail or Eurasian milfoil, it doesn’t branch at the surface as much as Eurasian, has half as many leaflet pairs as Eurasian and the leaves of Northern are rigid out of the water; Eurasian leaves are limp. Can quickly overtake a waterway.
An excellent habitat plant for aquatic life, it reproduces from seeds, buds and fragmentation. Chemical control is necessary once established.
