Yeap, around here we call them egg gourd plants! I had 1 over 30 yrs. before I had my daughter and lost my seeds-a few summers ago a flower friend brought me a plant and then I got to start growing them again. Their purple bloom is just like the blooms on a egg plant and the leaves also resemble the egg plant. Years ago people would use them in a hens nest for a nest egg-when they turn yellow they are ready to remove from the plant. I will bring my plants inside soon when I get time to repot them, hopefully I won't put them in shock.
