Hi Ravyn,
You should thank your neighbor and hug them for their wonderful advice.***:dude:* Just do a google search with the term:
Newt + trumpet vine and you'll read the nightmare I lived through with this vine.
Honeysuckle can also be a nightmare if you plant the wrong species.* Lonicera japonica aka Japanese honeysuckle aka Hall's honeysuckle aka Lonicera purpurea aka purple honeysuckle is the non-native invasive. It's the cream and yellowish fragrant one that grows wild and chokes out all other native plants.
There are some wonderful native honeysuckles that won't overtake your garden or the environment.* The native Lonicera sempervirens is what I have planted and is native to the eastern US.* I have two different named varieties and my hummers love it.* I do too. It blooms on and off in my zone 7 garden from the end of May until hard frost.* The birds also eat the berries and I've even had birds build a nest in it.* I also have a native yellow one (L. sempervirens 'John Clayton') but the hummers don't seem to like it as much.* Some of my favorite ones are:
Lonicera sempervirens

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
