I'm sitting out in my backyard this afternoon on a sunny spring day and as I look over toward the corner of my yard I see a puff of smoke. As time goes on I see more puffs of smoke coming from A 20' tall evergreen bush-tree that I have in my yard. I thought my neighbor was playing a joke on me by blowing puffs of smoke through a tube or something so I decided to go over and check it out. Upon closer investigation I realized that there were tiny little seed balls on the green part of the tree that were popping and sending out clouds of some kind of spores or something that looked like smoke. It made it appear as though the tree was catching on fire. Does anyone know about this phenomena? B
