A clinging plant is a type of plant that grows by attaching itself to other surfaces. The two most common examples of clinging plants are IVY and VINE. IVY is a three-letter word that refers to a woody evergreen plant with small yellowish-white flowers and lobed leaves. VINE is a four-letter word that refers to a climbing or trailing plant that typically has thin stems and leaves. Both IVY and VINE are known for their ability to cling to walls, fences, and other structures.
