I know that a lot of people believe and teach that Junipers are male and female and either one or the other. However in the research and study I have done over the years Junipers are monoecious, both sexes on the same tree, but my research is old and maybe that's not so. Any way the little with flowers are only pollen flowers. Most of my Shimpakus will do this and I have never once found a berry on any of them. In short unless you find berries don't worry about it.
