Salix caprea ... Goat Willow ... usually regarded as a weed tree in gardens ... it spreads all over the place with white fluffy seeds that drift in the air. It will grow fast, it grows into a pretty big tree ... good for wildlife and if you've got several acres of land that's fine ... not really suitable for most gardens.
