Pink Flower Tree/Bush

can you help me with the name of this bush/tree?
it is flowering right now.

thanks!

 

That's a flowering current.

 

There is a huge number of currant species in your area but I suggest that this might be red-flowering currant (Ribes sanguineum) which is native to your area (and probably also cultivated in gardens as it is even in Germany!)

 

Agreed; scientific name is Ribes sanguineum
