CRAZY gourd vine

At the beginning of the summer, my friend Lauren gave me a teeny little plant. It was 3" tall and she told me it was a gourd. I planted it in the back, didn't think much of it ...the thing has completely taken over my little hill, it is lush, and green and crazy. It's tendrils crawled up onto my pool area and actually entwined itself onto the pool cover (we never did open the pool this summer due to electrical problems... but that's a whole other story). This vine is reminicent of the monster plant "Seymore" in "Little Shop of Horrors." As you can see, the one gourd that is growing is the size of my HEAD!!!
