Can you tell us what zone you are in?

Are you 100% certain it's a vine?It looks like a hardy perennial Hibiscus to me. It's about to flower and that will tell you if it's a Hibiscus.

Are you sure it's a vine? It almost looks like a shrub from the photos.

If it is a vine, hops have similarly shaped leaves, but it's not one I've grown so I am not sure if yours is hops.

If you don't get an answer on this forum, try the Name that Plant forum which has a lot of quite knowledgeable folks contributing.

It's not hops. The flower buds are Hibiscus-like and at this stage hops would have long curling tendril like growth, not straight stems. I agree it doesn't appear to be a vine.
