Adhesive discs

Adhesive discs are actually modified tendrils, with the same toughness and resilience as tendrils but with an extra boost: Each tendril has a disc-like suction cup at the end. At any rate, these amazing structures afford a vine great adaptability — the vine can grab onto many kinds of supports, especially relatively smooth walls.

Though discs thrive with a smooth wall, they don't do well on rougher textures, such as brick, stone, and wood. Some of my favorite adhesive-disc vines include Boston ivy, crossvine, and Virginia creeper.
