Trumpet Vine is an aggressive, woody native vine that climbs by aerial rootlets the way English ivy does, hauling itself up trees, fences, and walls to 30 feet or more. From midsummer into fall it opens clusters of large, orange-red trumpet flowers that are one of the most reliable hummingbird magnets in the garden — few other plants pull in as many visits per day.
The trade-off for that vigor is a plant that's genuinely hard to contain. It spreads both by seed and by suckering roots that can send up new shoots ten feet or more from the parent vine, and established growth is heavy enough to pull down gutters, work into siding, and force apart mortar joints — give it a freestanding, sturdy arbor or pergola rather than a house wall or wood fence. Prune hard while dormant in late winter, since flowers form on new wood, and mow or dig out suckers as they appear through the growing season to keep the colony from spreading. Even within its native range it behaves like a weed in garden settings; well outside that range it has naturalized aggressively as far north as New England.
The sap irritates skin in sensitive people — long enough a reputation that it's earned the nickname cow-itch vine — so wear gloves when pruning or handling cut material.
