Honeysuckles (genus Lonicera; syn. Caprifolium Mill.) are arching shrubs or twining vines in the family Caprifoliaceae, native to the Northern Hemisphere. There are about 180 species of honeysuckle, with by far the greatest diversity in China, where over 100 species occur; by comparison, Europe and North America have only about 20 native species each. Widely known species include Lonicera periclymenum (European Honeysuckle or Woodbine), Lonicera japonica (Japanese Honeysuckle, White Honeysuckle, or Chinese Honeysuckle) and Lonicera sempervirens (Coral Honeysuckle, Trumpet Honeysuckle, or Woodbine Honeysuckle). Hummingbirds are attracted to these plants.

he leaves are opposite, simple oval, and from 1–10 cm long; most are deciduous but some are evergreen. Many of the species have sweetly-scented, bell-shaped flowers that produce a sweet, edible nectar. The fruit is a red, blue or black berry containing several seeds; in most species the berries are mildly poisonous, but a few (notably Lonicera caerulea) have edible berries. The plant is eaten by the larvae of some Lepidoptera species - see list of Lepidoptera that feed on honeysuckles.
