That wicked looking thing is an unripe African horned cucumber/ Kiwano jelly melon. They are so cool. This is my second time growing them. The first time I had forgotten about them/thought the vines were dead so I neglected them. I was walking around in my garden barefoot around thanksgiving and stepped on something sharp. When I looked down to my amazement there lay one of these fiendish fruits. If my memory serves correct, the jelly on the inside tastes like a banana meets a sour apple, meets a cucumber, with a squeeze of lemon.
They are beautiful vines too, and very aggressive. I had two seedling vines that took over a huge chunk of garden. I was initially concerned that the vines might not make it, but once they took off, they were unstoppable.
