I found this growing on our rock. It's some wild plant, pretty small, and flowers especially are very small. They're a bit sweet pea shaped, and the leaves are, well, you can see in the pics.
The flowers are pinkish, not very colourful. I think it's a nice little plant.
SOLVED: Small wild vine
No, L. sylvestris looks all different. Hmm.. :/ What if isn't a Lathyrus species at all?
Could be any number of pea flowers.
Try Vicia hirsuta, tenuissima, tetrasperma. Lathyrus palustris is another possibility. Maybe a wildflower book would give some indication
I looked at my Finnish flora book, didn't find anything like it. I'll try google again.
Baa, guess what, it's Vicia tetrasperma :D Have a look http://linnaeus.nrm.se/flora/di/faba/vicia/vicitet.html
Mäkivirvilä in Finnish. What a stupid name x)
Thanks again! Now I know how to call it.
