Here it is, the picture taken last year of our "Gothic Arch" with the moonflowers on it. We just love it and we are getting ready to do moonflower seeds for this year.
You can see the first pic when the vines were just getting started and the second shows how they grew and was smothering the whole structure. We made the mistake of planting two vines on each side, certainly won't do that this year and I will be doing selective pruning to keep the vines in check--may have more flowers that way, too.
