We need the location where this is growing. Did you just recently notice it? It looks like it's been around for awhile. Honeysuckle?

I’m in zone 6. The plant is relatively new and a rapid grower.

There is a honeysuckle close by, but the leaves do not look anything alike.

There are many species of honeysuckle, most invasive in my area.

Looks a lot like Lonicera tartarica.
