Trumpet Vine can be very aggressive in moist climates and it might be best not to encourage it, especially around structures. Hopefully someone in your area can weigh in. In my dry climate it's quite well behaved, but I've read many horror stories from others about trying to get rid of it. That's a pity, because bees and hummingbirds love it. There are some cultivars that don't spread so much, but it's hard to identify them without the flowers.
