DistributionMostly lower Piedmont, Sandhills, and Coastal Plain; also westward in Catawba, Gaston, Henderson, Macon, and Clay counties. Undoubtedly under-collected and will be found in most counties east of the Mountains.

NY to WV and MO, south to S.A. Originally from South America.
AbundanceFrequent to common, except rare in the Mountains and northwestern Piedmont. Many populations are very large and may cover much of the surface of a waterbody.
HabitatMostly in acidic, blackwater river systems such as impoundments, beaver ponds, sluggish backwaters and channels, natural lakes, interdune ponds and marshes.
PhenologyFlowering and fruiting late April-September.
IdentificationParrot-feather is easy to identify, due to its pastel green color and leafy (feathery) stems that partially rise above the surface. In our other milfoils, leaves are dull brownish green and normally do not extend above the surface. It is reported (Godfrey & Wooten 1981) that North American plants are all female and that they rarely produce flowers.
Taxonomic CommentsA synonym is M. brasiliense.
