spring snow?

The whole city is suddenly alive with pollen, white fluffy seeds like a thousand dandelions all blown about at once. It is thick enough to rest on your eyelashes, catch in your hair and get up your nose. It is everywhere - even down the metro. It was piled up in soft batches all over the floor of a building under construction I have just been visiting. I don't know what tree it comes from - can someone help here?

But even whilst it swirls like a fine soft snow, somehow it is hard to photograph. So, this is not actually meant to be a picture of a man in a funny hat on a scooter....
