I had some Thunbergia alata - Salmon Shades, growing on a fence last summer, and was wondering if they will reseed.

The seed pods, exploded sending the seeds everywhere so I will have them all over the place if the seeds can survive Zone 5 winters.

If they can't survive here, does anyone know in what zone they do reseed? I have a friend in zone 7 that wants some seeds, but I wouldn't want to send them without a warning if they can become invasive.
