Betula nigra Heritage® ('Cully')
Heritage® River Birch

Birches are monoecious (translation = "one house"), meaning that separate male and female flowers occur on the same tree. In this image, the pendulous catkin (staminate or male inflorescence) on the left sheds pollen, some of which may fertilize the ovules within the upright and nearly invisible pistillate (female) inflorescence in the center.
