Thanks for your question.

Yes, Virginia Creeper (Parthenocissus quinquefolia) can climb concrete walls without any additional support. This vine has specialized structures called adhesive tendrils or suction-cup-like tips that allow it to adhere firmly to surfaces such as concrete, brick, or wood. These tendrils can anchor the vine securely as it grows.

Here are some other thoughts:

1). You could also install a trellis or a wire support. I have Virginia Creeper growing along a ten-foot stretch of a concrete wall that is about six feet tall. I cut this back each fall to about six inches above the ground.

2). Virginia Creeper grows quickly, so regular maintenance is needed to prevent it from becoming invasive. I have found that my fall pruning is more easily done when a support system is used rather than trying to pull the plant off the concrete wall.

3). Another reason why I prefer a support system is that the tendrils may leave marks or residue on the wall. On older or porous concrete, they might even pull off bits of the surface when removed.

4). I enjoy the changes that occur in the plant as the season progresses. During midsummer, it has small, greenish-white flowers that grow in wide clusters. In late summer, berries develop that are initially green and then turn blue-black. In the fall, the leaves turn bright red or purple.

It’s a fun plant to have around and should do the job for you. Just be warned, it rapidly spreads.

Good luck. Thanks for using our forum.
