Keep or kill?
The photo is of a grape vine. Since there is only one planted I am assuming it is a table grape, hopefully one you will enjoy the taste of. Here is the link to an Oregon State University Extension publication that discusses how to grow table grapes. https://catalog.extension.oregonstate.edu/sites/catalog/files/project/pdf/ec1639.pdf Grape vines can get quite large if not pruned properly so in that sense I guess it could become invasive to the space allotted for it to grow. The publication discusses pruning and training of grape vines.
