The Japanese Honeysuckle (Lonicera japonica) is a species of honeysuckle native to eastern Asia including China (northern and eastern P.R.China and Taiwan), 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?1.2 in) broad. The flowers are double-tongued, opening white and fading to yellow, and sweetly vanilla scented. The fruit is a dark blue berry 5?8 millimetres (0.20?0.31 in) diameter containing numerous seeds. The Japanese Honeysuckle flower is of high medicinal value in traditional Chinese medicine, where it is called r?n d?ng t‚ng (Chinese: ???; literally "winter enduring vine") or j?n y¡n hu? (Chinese: ???; literally "gold silver flower"). It has antibacterial and anti-inflammatory properties, and is used (often in combination with Forsythia suspensa) to dispel heat and remove toxins, including carbuncles, fevers, influenza and ulcers. In Korean, it is called geumeunhwa. The dried leaves are also used in traditional Chinese medicine. Hardiness zone: 4-9
