The sweet pea, Lathyrus odoratus, is a flowering plant in the genus Lathyrus in the family Fabaceae (legumes), native to Sicily, southern Italy and the Aegean Islands

Seeds
It is an annual climbing plant, growing to a height of 1–2 metres (3 ft 3 in–6 ft 7 in), where suitable support is available. The leaves are pinnate with two leaflets and a terminal tendril, which twines around supporting plants and structures, helping the sweet pea to climb. In the wild plant the flowers are purple, 2–3.5 cm (3⁄4–1+1⁄2 in) broad; they are larger and very variable in colour in the many cultivars. Flowers are usually strongly scented.

This article is about climbing plants in general. For the short-form video service, see Vine (service). For grapevines, see Vitis. For other uses, see Vine (disambiguation).
A vine (Latin vīnea "grapevine", "vineyard", from vīnum "wine") is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas or runners. The word vine can also refer to such stems or runners themselves, for instance, when used in wicker work.

In parts of the world, including the British Isles, the term "vine" usually applies exclusively to grapevines (Vitis), while the term "climber" is used for all climbing plants.

Certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available.

A vine displays a growth form based on very long stems. This has two purposes. 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. 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. There are some tropical vines that develop skototropism, and grow away from the light, a type of negative phototropism. Growth away from light allows the vine to reach a tree trunk, which it can then climb to brighter regions.

The vine growth form may also enable plants to colonize large areas quickly, even without climbing high. This is the case with periwinkle and ground ivy. 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. A vine can root in the soil but have most of its leaves in the brighter, exposed area, getting the best of both environments.

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.It has evolved independently in several plant families, using many different climbing methods,such as:

twining the stem around a support (e.g., morning glories, Ipomoea species)
by way of adventitious, clinging roots (e.g., ivy, Hedera species)
with twining petioles (e.g., Clematis species)
using tendrils, which can be specialized shoots (Vitaceae), leaves (Bignoniaceae), or even inflorescences (Passiflora)
using tendrils which also produce adhesive pads at the end that attach themselves quite strongly to the support (Parthenocissus)
using thorns (e.g. climbing rose) or other hooked structures, such as hooked branches (e.g. Artabotrys hexapetalus)
The climbing fetterbush (Pieris phillyreifolia) is a woody shrub-vine which climbs without clinging roots, tendrils, or thorns. 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 fetterbush then sends out branches that emerge near the top of the tree.[9]

Most vines are flowering plants. These may be divided into woody vines or lianas, such as wisteria, kiwifruit, and common ivy, and herbaceous (nonwoody) vines, such as morning glory.

One odd group of vining plants is the fern genus Lygodium, called climbing ferns.[10] The stem does not climb, but rather the fronds (leaves) do. The fronds unroll from the tip, and theoretically never stop growing; they can form thickets as they unroll over other plants, rockfaces, and fences.
