Hummingbird vine is also known as trumpet creeper, cow itch vine and more commonly trumpet vine. I have A 12 (w)' X 8' (h) trellis cover with trumpet vines. Second generation 1st was blown over by wind and rain it was so big and heavy. I have seen five or six vines "braided" and raised on a single post with a spoked wagon wheel at the top. It can be considered invasive if left on its own. I have to treat many to get rid of them when the vine seeds itself in the lawn, I hand eliminate them when it is in the flower beds. I will gladly send you seed pods should you care to start it this way. Send me a mailing address P.S. I have never seen humming birds around it that I can recall. Might have had visitors during migration David Phillips jjdgp AT att.net
