Symphoricarpos albus

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.

Ipomoea [purpurea?]

 IMG_5891 [Ipomoea purpurea]

Ipomoea is the largest genus in the plant family Convolvulaceae with about 500 species. The flower above most probably belongs to the species of purpurea but I leave the exact identification to the experts.
 
With identification put aside, I believe no matter how you call the flower, its beauty remains unquestionable [imho].
 
It is said to have originated from Mexico and Central America but apparently has spread almost all over the world.
