Hovenia dulcis

Hovenia dulcis, or the oriental raisin tree, is a hardy tree found in Asia, from Eastern China (萬壽果; pinyin: wànshòuguǒ) and Korea (헛개나무, heotgae namu) to the Himalayas (up to altitudes of 2,000 m), growing preferably in a sunny position on moist sandy or loamy soils. The tree known for its health benefits when consumed in tea, introduced as an ornamental tree to several countries, also bears edible fruit. It is considered to be one of the most pervasive invaders in Brazilian subtropical forests.
