The stem does not climb, but rather the fronds (leaves) do. One odd group of vining plants is the fern genus Lygodium, called climbing ferns. These may be divided into woody vines or lianas, such as akebia wisteria, kiwifruit, and common ivy, and herbaceous (nonwoody) vines, such as morning glory. The fetterbush then sends out branches that emerge near the top of the tree. It directs its stem into a crevice in the bark of fibrous barked trees (such as bald cypress) where the stem adopts a flattened profile and grows up the tree underneath the host tree's outer bark. The climbing fetterbush ( Pieris phillyreifolia) is a woody shrub-vine which climbs without clinging roots, tendrils, or thorns. climbing rose) or other hooked structures, such as hooked branches (e.g. using tendrils which also produce adhesive pads at the end that attach themselves quite strongly to the support ( Parthenocissus).using tendrils, which can be specialized shoots ( Vitaceae), leaves ( Bignoniaceae), or even inflorescences ( Passiflora).with twining petioles (e.g., Clematis species).by way of adventitious, clinging roots (e.g., ivy, Hedera species).twining the stem around a support (e.g., morning glories, Ipomoea species).It has evolved independently in several plant families, using many different climbing methods, such as: The evolution of a climbing habit has been implicated as a key innovation associated with the evolutionary success and diversification of a number of taxonomic groups of plants. A vine can root in the soil but have most of its leaves in the brighter, exposed area, getting the best of both environments. It is also an adaptation to life in areas where small patches of fertile soil are adjacent to exposed areas with more sunlight but little or no soil. This is the case with periwinkle and ground ivy.

The vine growth form may also enable plants to colonize large areas quickly, even without climbing high. Growth away from light allows the vine to reach a tree trunk, which it can then climb to brighter regions. There are some tropical vines that develop skototropism, and grow away from the light, a type of negative phototropism. This has been a highly successful growth form for plants such as kudzu and Japanese honeysuckle, both of which are invasive exotics in parts of North America.

A vine may use rock exposures, other plants, or other supports for growth rather than investing energy in a lot of supportive tissue, enabling the plant to reach sunlight with a minimum investment of energy. Ī vine displays a growth form based on very long stems. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available. Certain plants always grow as vines, while a few grow as vines only part of the time.
