Which is the fastest growing tree in central Europe?
Answers:
all poplars, definitely. but actually quite often there are northamerican species of poplar cultivated here apart from the native ones.
also birch
the wood of both is very soft, that can enable fast growth rates. but you cant make good furniture of it, can you...
Other answers:
The human family tree. Other than that I don't know, sorry.

I would say a poplar tree. They are fast growing but have very weak wood, so if you are thinking about planting them, don't plant them too close to your house!
All poplars, but You could try with Populus nigra L. or Black Poplar, or willow poplar
