Hungarian vetch is rather like what I call purple vetch (V.americana)or harry vetch -(V . villosa).
Vicia pannonica the Latin name for Hungarian vetch -used here as a forage crop inter planted with some other stuff
the problem with the photo is it shows a flower spike with flowers encircling the stalk , all the vetches I am familiar the flowers are on one side
The flowers form is like red clover ? but not quite
There are tons of vetches maybe one I am not familiar with
Good luck
I will watch for updates
:
....as fort the other flower sweet mignonette , If that is Reseda odorata , I have grown that flower and it is not the second photo
