Japanese Wineberry, Wineberry, or Wine Raspberry

Rubus phoenicolasius (Japanese Wineberry, Wineberry, or Wine Raspberry) is a species of raspberry (Rubus subgenus Idaeobatus) native to northern China, Japan, and Korea.[2] The species was introduced to Europe and North America as an ornamental plant and for its potential in breeding hybrid raspberries. It has subsequently escaped from cultivation and become naturalised and sometimes invasive in parts of Europe and eastern North America
