Flowers of this plant are very small and white in color. Almost all plants of this species are female. Seeds are not produced in any North American plants. Parrotfeather reproduces asexually. New plants grow from fragments of already rooted plants. There is no real predator to the parrotfeather, so it grows out of control. While part of the milfoil family, it is easily distinquishable from other milfoils as it grows below and above the surface of the water.
