Cottonwood trees produce a tiny parachute, made from a bit of cotton, and attach it to each seed. That way they get carried far and wide by the wind. It falls around the same time each year and looks like snow.
This nature video was made at Fresh Pond Reservation, FPR, Cambridge, Massachusetts, Tuesday, June 6, 2006, with a Canon S80.
Not really. Everybody tries to reproduce. This is just the cottonwood tree's way to do it. Each of those "flakes" is a seed.
