Honeysuckles are arching shrubs or twining vines in the family Caprifoliaceae, native to northern latitudes in North America and Eurasia. Approximately 180 species of honeysuckle have been identified in North America and Eurasia.
Honeysuckles are valued as garden plants, for their ability to cover unsightly walls and outbuildings, their profuse tubular flowers in early summer, and the intense fragrance of many varieties. Most species of Lonicera are hardy twining climbers, with a minority of shrubby habit. Some species are tender and can only be grown outside in subtropical zones. The leaves are opposite, simple oval, 1–10 cm long; most are deciduous but some are evergreen. Many of the species have sweetly scented, bilaterally symmetrical flowers that produce a sweet, edible nectar, and most flowers are borne in clusters of two (leading to the common name of "twinberry" for certain North American species).
