Lonicera is a genus of shrubby or climbing plants in the family Caprifoliaceae. They are native to North America, Europe, and Asia. They grow as climbing shrubs or climbers and can reach heights of up to 5 m. They have semi-evergreen foliage, with part of the leaves remaining on the plant in winter. The leaves are oppositely arranged, simple, oval, 3-8 cm long. Most species have fragrant inflorescences. Fruits are spherical or elongated, dark berries containing several seeds. They are planted in parks, gardens, as wall coverings, fences, or pergolas. In some parts of Asia, lonicera (L. japonica) is an invasive species. The name of the genus comes from the botanist Adam Lonicera.
