I have it and yes terrible idea . There is a huge difference in strains . I bought some and they were very invasive . Lots of suckers . I now have some seed grown ones that are better behaved . Got fence row seed along crop fields . Less suckers and shorter vines . Still a pain but manageable .Anybody have trumpet vine? I like the look of it and my sister's neighbor gave me a large runner she pulled and potted up for me. I'm thinking about planted it by the garden gates and training it up the arbor over that surrounds the gates. Is this a terrible idea? Is it a hard to keep in check as some say it is?
