Bjørn. IIRC the white blooms are Brambleberry (Brombeere).
Gary. Fascination came from a meadow with scattered fruit trees, mostly old apple varieties and fruit trees. They make honey and I design the labels for the honey:

The book I am just writing covers that topic and because of the fascination of that topic I am a regular to botanical gardens (as I am to Pipe Organs and Churches in General).
I still have another bee set to be developed from the botanical garden in Bonn. Note that I sometimes post shots of flower flies who are no bees and no wasps but sometimes you need and expert to tell these apart, because they mimic the other species.
Photographically the flower varieties in a botanical garden are much more interesting than the ones I found in the defunct gravel pit, that was more like a desert with very few animals and very few different kinds of plants. Alas scientifically the "half desert" was much more rewarding because the "Hosenbienen" dig their caves with many rooms and have quite an interesting look.
I still have many precious shots to be developed from that shooting too.
