What plant species is this?
Its stalk looks like a grapevine, but the leaves & flowers not. It bloomed this week (Mid-June). I have found it in Turkey, Amasya.
If you want, I can add more shots of plant.
That is a kind of honeysuckle. The picture below is for Japanese honeysuckle (Lonicera japonica), but your specimen is different in the way the flowers are arranged and that the distal-most paired leaves are clasping the stem.
It might be Lionicera periclymenum, or Lonicera etrusca (there are about 150 species of honeysuckle); L. etrusca is pictured below (the color is irrelevant) which is native to Europe.
