Red Cucumer (Moi) Blossoms

I planted a Red Cucumber (Moi) in my side yard, as well as on my second floor balcony, but the plant in my side yard is starting to flower. I'm so excited. It has attached itself to my fence and growing in all directions. There is also a Bitter Melon (Goya) plant growing on the fence. I did not plant the Goya, but this is the second year it grew. I never got any Goya from it, but it is amazing it continues to appear.
