Small find!

After a weekend of woodland delights and foraging walks (backblips pending), I made this discovery as I got home from work today. Outside my flat there is a *tiny* patch of untended wilderness (aka weeds) living under a silver birch in the otherwise concrete paradise.

This plant, if I have identified it correctly, is common vetch. Part of the pea family. And the little shoots/flowers at least are edible :)

As this one is a newly learned plant for me, I'm not 100% on its ID. Perhaps someone in the know will confirm or correct me. :)
