Funny, it's seems to be the female tree (the one with the fruits) that are the pollen blowers. I can send you a video of it, although the tree hardly had any leaves on it. The male tree (the one with that unique leaf shape) is not nearly as tall and it seems to be the only one so far in my neighbors yard. I did happen to go to a local city park in Brooklyn an noticed the male paper mulberrys lined along the outside edges and it appears they're already starting to choke the life out of some adjacent trees (whose idea was it to put such an invasive tree in a city park?)
