For me: nigella, calendula, forgetmenots, mallow, columbine, and also chamomile and dill. Which ones will you come up where they want to?
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 ๐
