The cattail is one of the most easily recognized of all our wild
plants. It grows in marshes all over the world. Many parts of the
plant are edible.
The male flowers (which produce pollen) grow at the top of the flower
spike. The female flowers occur just below this, in a densely packed
cylinder. The individual flowers are almost microscopic in size.
As the seeds mature the cylinder turns from green to brown, and
breaks apart into fluffy down which carries the tiny seeds away in
the wind.
