Please tell me!

Went on a little personal photo shoot at Lyon's St.Exupery airport today because the building is so amazing. Took a dozen or so shots (see extre photo) but on the way stopped off at some fields to watch the planes take off and saw this bush with these blue 'berries'.
 So - now I have the question of determining what exactly they are. I though bitter aloes, but apparently not. Not juniper neither - I don't think. Surely someone here can help? Mum?
