Absolutely not grapevine. The people we bought our house from had let two grapvines grow wild. I don’t think we will ever be able to get rid of it all. They strangled a whole hedge of lilac, which thankfully is now making a comeback 😍

Tall verbena. It reseeds everywhere. It’s tall and thin with little tufts of flowers on the top, so it never crowds anything out and it looks like little floating puffs of purple. My garden is mostly native to the mid atlantic region in the US, but I can’t bring myself to get rid of that Brazilian native.
