Myriophyllum aquaticum is a flowering plant, a vascular dicot, commonly called parrot's-feather and parrot feather watermilfoil.
Parrot feather is native to the Amazon River in South America, but it can now be found on every continent except Antarctica. It is thought that this plant was introduced to North America around the late 1800s. It was first discovered in the United States in the 1890s in Washington D.C. Parrot’s feather typically grows in freshwater streams, ponds, lakes, rivers, and canals that have a high nutrient content. During the 20th century it colonized areas in South Africa, Japan, England, New Zealand, and Australia. As it prefers a warmer climate, it is chiefly found in the southern parts of the United States.
Parrot feather is a perennial plant. Parrot feather gets its name from its feather-like leaves that are arranged around the stem in whorls of four to six. The emergent stems and leaves are the most distinctive trait of parrot feather, as they can grow up to a foot above the water surface and look almost like small fir trees. The woody emergent stems grow over 5 feet long and will extend to the bank and shore. Attached to the Parrot feather are pinkish-white flowers that extend approximately 1/16 inches long. As the water warms in the spring, parrot feather begins to flourish. Most plants flower in the spring; however, some also flower in the fall. Almost all plants of this species are female, in fact there are no male plants found outside of South America. Seeds are not produced in any North American plants. Parrot feather reproduces asexually. New plants grow from fragments of already rooted plants. The plant has whorls of feathery blue-green to waxy gray-green leaves deeply cut into many narrow lobes.
