This is a vine with orange flowers (trumpet like) Have never seen this one before.
your vine is called Ipomoea coccinea, sometimes also called Quamoclit coccinea, and it is related to the cultivated cypress vine. Both are a type of morning glory, and the hummingbirds love it. Some people call it ‘redstar’.
