Myriophyllum aquaticum
Parrot Feather Watermilfoil
Not native to Florida
A frequent aquatic plant of ponds, lakes and canals in about half of Florida counties scattered throughout the state. Native to South America, it now ranges across the southern part of the United States, up the mid-Atlantic into Connecticut and New York, also Ohio & Pennsylvania, all of the west coast states, including inland into Idaho and Montana. Also found in British Columbia.
Leaves are comblike, appearing in whorls of four to six around the stem. Unlike the other Myriophyllum species, the submerged and above water leaves are the same. The leafy branches of Parrot feather watermilfoil grow mostly on and above the water and across the ground of the shore, becoming erect and more leafy at the ends. Stems may be 1.5 m (5 ft.) long.
