Schisandra chinensis

Schisandra chinensis (五味子 in Chinese, pinyin: wǔ wèi zi, literally "five flavor berry") is a deciduous woody vine hardy to USDA Zone 4 and is dioecious, meaning individual plants are either male or female, thus both male and female plants must be grown if seeds are desired. It is very tolerant to shade. Its Chinese name comes from the fact that its berries possess all five basic flavors: salty, sweet, sour, pungent (spicy), and bitter.
