I'm in Massachusetts, and recently moved into a new house. We have a vine in the yard which I have been having trouble identifying so far, and I was hoping someone here might know.
It has not yet flowered, so I am unable to give any information on the flower.
When I pull the roots, they are long runners, and smell sweet.
It likes climbing things, as may be obvious from the photos, and I first noticed it because it was coming up in the lawn. It appears to like to be in similar places to a sweet pea vine and a (probably) bittersweet nightshade vine.
Basically, I'm not sure if it's something we want to be keeping, or trying to completely eradicate. (I don't actually think I can completely eradicate it unless I destroy the yard, mind you)
