Don't have the Alamo Vine seeds for you but yes, I also have dreams of what I will build and grow someday. This year I finally was able to realize one of my dreams. Here is my "mini-pergola planter box" which I built with my own two hands and some power tools. There was wire fence material added to the two ends after this photo was taken. I designed it for vine plants such as cucumbers or small melons with space for lettuces, radish and other faster growing plants while the vines grow to cover the top.
Don't give up your dream.
