Virginia creeper can be used as a shading vine for buildings on masonry

 walls. Because the vine, like its relative Boston ivy, adheres to the surface by disks rather than penetrating roots, it will not harm the masonry but will keep a building cooler by shading the wall surface during the summer, saving money on air conditioning. As with ivy, trying to rip the plant from the wall will damage the surface; but if the plant is first killed, such as by severing the vine from the root, the adhesive pads will eventually deteriorate and release their grip
