These beautiful, fast-growing vines may look dainty, with their delicate compound leaves and dangling clusters of cup-shaped blooms - and they are anything but! Originally native to Northern Japan, these aggressive vines are beautifully evergreen in the Pacific Northwest and warmer areas and deciduous in colder climates. The abundant May flower clusters are very fragrant. The vine produces bizarre looking five-inch (occasionally much larger) long pink, or blue-skinned fruit.
