Wall-climbing plants are plants that have adapted to grow on vertical surfaces, such as walls. Two examples of wall-climbing plants are IVY and VINE. IVY is a woody evergreen plant with small leaves and aerial roots that allow it to cling to walls and other surfaces. Vines are plants that climb by twining their stems or by attaching themselves with tendrils or suckers. They can also be trained to grow along a trellis or other structure.
