Parthenocissus tricuspidata

Parthenocissus tricuspidata is a species of flowering plant in the grape family (Vitaceae) native to eastern Asia (Korea, Japan, and northern and eastern China), where it thrives in floodplain bushes, riverside woodland and moist mountain mixed forests. Although unrelated to true ivy, it is commonly known as Boston ivy, grape ivy, Japanese ivy, and also as Japanese creeper, and by the name woodbine (though the latter may refer to a number of different vine species). The specific epithet tricuspidata means three-pointed, referring to the leaf shape. Boston ivy is readily distinguished from the Virginia creeper (Parthenocissus quinquefolia) by its simple leaves with pointed lobes (Virginia creeper leaves are divided into five separate leaflets)....read more on Wikipedia.
