You could always eat the seeds, if they don't germinate, you might have to run em through a second time lol seriously though you can acid scarify them or take hardwood cuttings http://www.wildflower.org/plants/result.php?id_plant=RHCOIt is winged sumac and I have been trying to get more of it started around my area, some facts I have found. The seeds need to go through the digestive tract of a bird or animal before they can germinate, and fire can also activate germination. Since I can't just plant it, I have taken to scattering it around the open edges, with some but not overwhelming success. If it is cut back it will send up more shoots the next year. After getting started it will develop dense thickets and will die out after ten or fifteen years. I like it most because it blooms during my dearth and seems to provide copious amounts of nectar when hardly any other exist. The bloom dates must proceed from north to south like goldenrod since it won't bloom here for a couple of weeks.
Mix those seeds with the wildbird seed n put it in your bird feeder.The seeds need to go through the digestive tract of a bird or animal before they can germinate.
