We do have Trumpet Vine (Campsis radicans) here but it hasn't been a problem for us. It is mostly present down in the bottomland and that's zone 5 for us. Thankfully we don't have any invasive weeds around our zone 1-4 areas. The worst we deal with is bermuda (occasionally) and Yellow Nutsedge (Cyperus esculentus) - the latter is controlled with Sedgehammer and we are winning the battle!
