I have seen this shrub in mid April in a park in Western Germany and I remember the flowers were quite fragrant.
Do you know what it is?
Viburnum farreri - one of the few non-white viburnums. Robust shrub originally from China, but planted in gardens all over the world.
The main blooming time is April/May, but often first flowers open during late fall and winter, when the branches are bare. (Can be confusing when searching for images.)
