|IMG_5893 [Symphoricarpos albus]|
Native to North America and much of Canada but also naturalized in many other countries. I have never seen it before in Greece.
By the way, its name derives from Greek συν + φέρω + καρπούς meaning “bearing fruits together”. The picture above seems to justify this name.
