Lonicera japonica, the Japanese honeysuckle (suikazura スイカズラ/吸い葛 or 忍冬 in Japanese; jinyinhua 金银花 or rendongteng 忍冬藤 in Chinese, 인동 or 겨우살이덩굴 in Korean, kim ngân hoa in Vietnamese) 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 (33 ft) high or more in trees, with opposite, simple oval leaves 3–8 centimetres (1.2–3.1 in) long and 2–3 centimetres (0.79–1.18 in) broad
This species is often sold by American nurseries as the cultivar 'Hall's Prolific' (Lonicera japonica var. halliana). 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.
The dried leaves and flowers (Flos Lonicerae Japonicae) are employed in traditional Chinese medicine, being used to treat fever, headache, cough, thirst and sore throat
