Japanese Honeysuckle

Lonicera japonica

The Japanese Honeysuckle is a species of honeysuckle native to eastern Asia including China, Japan and Korea. It is a twining vine able to climb up to 10 metres high or more in trees, with opposite, simple oval leaves 3–8 centimetres long and 2–3 centimetres broad. The flowers are double-tongued, opening white and fading to yellow, and sweetly vanilla scented. The fruit is a globose dark blue berry 5–8 millimetres diameter containing numerous seeds.

It is an invasive species in a number of countries.

Naming

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.

In the United States Japanese Honeysuckle is classified as a noxious weed in Texas, Illinois, and Virginia, and is banned in New Hampshire. It grows extremely rapidly in parts of America such as southwestern Ohio and is virtually impossible to control in naturalized woodland edge zones due to its rapid spread via tiny fruit seeds. It forms a tall dense woody shrub layer that aggressively displaces native plants. It is also very difficult to manage in semi-wild areas, such as in large rural yards.

It is listed on the New Zealand National Pest Plant Accord as an unwanted organism.

It can be controlled to some degree via labor-intensive methods such as cutting or burning the plant to root level and repeating at two-week intervals until nutrient reserves in the roots are depleted. It can also be controlled through annual applications of glyphosate, or through grubbing if high labor and soil destruction are not of concern. Cutting the honeysuckle to within 5–10 cm of the ground and then applying glyphosate has proven to be more effective, provided that the mixture is rather concentrated and is applied immediately after making the cut.

Uses

This species is often sold by American nurseries as the cultivar 'Hall's Prolific' . It is an effective groundcover, and has pleasant, 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.

In both its native and introduced range, Japanese Honeysuckle can be a significant source of food for deer, rabbits, hummingbirds and other wildlife.

The cultivar 'Halliana' and the variety ''L. japoinica'' var. ''repens'' have both gained the Royal Horticultural Society's Award of Garden Merit.
