Almost all plants of this species are female. Flowers of Parrotfeather are very small and white in color. Seeds are not produced in any North American plants. Parrotfeather reproduces asexually, with new plants growing from fragments of already rooted plants. Parrotfeather’s leaves are long and light green to blue green in color. There is no real predator to the parrotfeather, so it grows out of control. While part of the milfoil family, it is easily distinguishable from other milfoils as it grows both below and above the surface of the water.
