Anna - in my NC experience the trumpet vine shoots did not come up close to the parent plant only - they emerged long distances away (in an acre garden) - little devils poking up in unexpected places. Since it was a garden and not a mowed lawn, it became a real problem. Each shoot had to be dealt with. I could not kill the parent plant as it was across the back fence in someone's yard. But that would not have solved the shoot problem as the roots would live for years. I think there may be more domesticated varieties that are safer to plant. But the wild Southern trumpet vine is a real character - it will definitely outlive you (much like kudzu).
