Lonicera japonica, known as Japanese honeysuckle [2] and golden-and-silver honeysuckle, [3] is a species of honeysuckle native to East Asia, including many parts of China. It is often grown as an ornamental plant, but has become an invasive species in a number of countries. It is used in traditional Chinese medicine.

Description

Lonicera japonica is a twining vine [4] able to climb up to 10 m (33 ft) high or more in trees, with opposite, simple oval leaves 3–8 cm (1+143+14 in) long and 2–3 cm (341+14 in) broad. When its stems are young, they are slightly red in color and may be fuzzy. Older stems are brown with peeling bark, and are often hollow on the inside. [5]

The flowers are double-tongued, opening white and fading to yellow, and sweetly vanilla scented. The fruit, which is produced in fall, [5] is a black spherical berry 3–4 mm (18316 in) diameter containing a few seeds. [6]

Chemistry

Lonicera japonica contains methyl caffeate, 3,4-di-O-caffeoylquinic acid, methyl 3,4-di-O-caffeoylquinate, protocatechuic acid, methyl chlorogenic acid, and luteolin. The two biflavonoids, 3′-O-methyl loniflavone and loniflavone, along with luteolin and chrysin, can be isolated from the leaves. [7] Other phenolic compounds present in the plant are hyperoside, chlorogenic acid, and caffeic acid. [8] The two secoiridoid glycosides, loniceracetalides A and B, can be isolated, together with 10 known iridoid glycosides, from the flower buds. [9] The plant also contains the saponins loniceroside A and B [10] and the anti-inflammatory loniceroside C. [11]

Subspecies

There are three subspecies of Lonicera japonica:

Ecology

The flowers can also be a significant source of food for deer, rabbits, hummingbirds, and other wildlife. [15]

As an invasive species

Japanese honeysuckle has become naturalized in Argentina, Australia, Brazil, Mexico, New Zealand, and much of the United States, including Hawaii, as well as a number of Pacific and Caribbean islands. It is classified as a noxious weed in 46 states, Prohibited to be bought and sold in Connecticut, Illinois, Massachusetts, and Vermont, and banned in Indiana and New Hampshire. [16] [17] [18] It is listed on the New Zealand National Pest Plant Accord as an unwanted organism. [19]

Lonicera japonica was initially brought to the U.S. from Japan in the early 1800s as an ornamental plant. It is still deliberately planted in the U.S. for reasons such as erosion control or forage for deer, but has become invasive in many areas. [5] It prefers to invade areas that have been disturbed, such as roadsides or floodplains. It will generally only invade forests when the canopy has been opened by logging or fallen trees, as it grows less vigorously in the shade. [20] Once it has invaded an area, Lonicera japonica grows rapidly and outcompetes native plants for sunlight and nutrients. [5] It proliferates using both sexual and vegetative reproduction, producing seeds that are spread by animals and expanding locally via rhizomes. [21] Eventually, it will form a dense thicket which prevents other plant species from germinating in that area. [5] Due to its suppression of germination in the understory, Lonicera japonica also prevents the regeneration of trees. [22]

Management of invasive Lonicera japonica has been achieved through a variety of means. Small patches can be removed by hand, or using simple digging tools, [21] but all plant parts including roots and rhizomes must be removed to prevent resprouting. [5] Larger patches can be removed through repeated mowing, but application of herbicide is also recommended to prevent regrowth. [21] There has been some study of using controlled burns to remove L. japonica, but the underground portion of the plant is usually able to survive and resprout, limiting the effectiveness of this method. [5] Browsing by herbivores may limit its growth, but is unlikely to fully eliminate it. [22]

Biological control

The EPA of New Zealand approved the release of Limenitis glorifica butterflies in 2013 as a biological control for Lonicera japonica. This butterfly is host specific for Japanese honeysuckle, but it may incidentally feed on other closely related plants, including Himalayan honeysuckle Leycesteria formosa . [23] Oberea shirahatai is a Japanese honeysuckle host-specific beetle that feeds on the stems and leaves of Japanese honeysuckle. It was released in New Zealand in 2018 as another L. japonica-specialist biological control. [24]

Cultivation

Even though it is a highly invasive and destructive plant, [25] this species is often sold by American nurseries as the cultivar 'Hall's Prolific' (Lonicera japonica var. halliana),[ citation needed ] and in the UK as the cultivar 'Halliana'. The cultivar is also known as Hall's Japanese honeysuckle. [26] It is an effective groundcover and has strong-smelling flowers. It can be cultivated by seed, cuttings, or layering. In addition, it will spread itself via shoots if given enough space to grow. The variety L. japonica var. repens [27] has gained the Royal Horticultural Society's Award of Garden Merit. [28]

Toxicity

All parts of the plant other than the flower nectar have the potential to be toxic. [29]

Uses

Japanese honeysuckle flowers are edible to humans and appreciated for their sweet-tasting nectar.[ citation needed ]

Herbal medicine

In traditional Chinese medicine, [30] Lonicera japonica is called rěn dōng téng ( 忍冬 ); [30] literally "winter enduring vine") or jīn yín huā [30] (Chinese : ; literally "gold-silver flower", in reference to the presence of flowers of different age on the same plant as each flower change from white (silver) to yellow (gold)).[ citation needed ] Alternative Chinese names include er hua (二花) and shuang hua (雙花), meaning double-[color] flowers. [31] [32]

Saponins are bitter-tasting, usually toxic plant-derived secondary metabolites. They are organic chemicals and have a foamy quality when agitated in water and a high molecular weight. They are present in a wide range of plant species throughout the bark, leaves, stems, roots and flowers but particularly in soapwort, a flowering plant, the soapbark tree, common corn-cockle, baby's breath and soybeans. They are used in soaps, medicines, fire extinguishers, dietary supplements, steroid synthesis, and in carbonated beverages. Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin and quillaia, a bark extract used in beverages.

The flowers are followed by black berries. The Latin specific epithet similis means "similar to". It is similar in appearance to L. japonica, but larger and more robust. The name delavayi honours the French missionary and botanist Père Jean Marie Delavay (1834-1895).
