My guess is that you have two different varieties and that is not necessarily a bad thing. Sometimes the male pollinator is a different variety than the females. I have two females and one male also. I believe my variety is Anna or maybe Artic. Mine are about 12 years old, but their development was stunted by the fact that I moved them after 4 years and after that I pruned them too aggressively in the winter to allow budding. This year I should get my first fruit, since I have guite a fruit at this time. Hope the squirrels do not find them. My vines are green with a redish/purple vein that highlights the color. I am attaching a picture. The kiwis are to the left of the picture supported on "T" trellisses.
