Leaves partly evergreen, very narrow, less than 1/4 inch wide and up to 3 inches long. Male and female flowers on separate plants. Female flowers inconspicuous, silky, in small, greenish white heads which appear to be individual flowers, these arranged in large clusters up to 1 foot or more long and 8 inches wide, resembling silky plumes in October and November.
