A fast-growing, twining woody vine native to East Asia, widely planted as an ornamental and groundcover, but invasive in many regions. Its key to growing is containing its spread, since it readily runs and self-seeds.

About
Lonicera japonica, known as Japanese honeysuckle and golden-and-silver honeysuckle, 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.
How to grow it
Even though it is a highly invasive and destructive plant, this species is often sold by American nurseries as the cultivar 'Hall's Prolific' (Lonicera japonica var. halliana), and in the UK as the cultivar 'Halliana'. The cultivar is also known as Hall's Japanese honeysuckle. 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 has gained the Royal Horticultural Society's Award of Garden Merit.
Safety
All parts of the plant other than the flower nectar have the potential to be toxic if consumed in a very large quantity for its saponin.
Where it grows
The flowers can also be a significant source of food for deer, rabbits, hummingbirds, and other wildlife.
Uses
Japanese honeysuckle flowers are edible to humans and appreciated for their sweet-tasting nectar.
