This has self-seeded in my garden, but I've only seen the catkins this year. Can someone identify it for me please? Most tree identification sites seem to cover catkins that hang down, but these are all pointing up, and look very jolly. Thanks
Looks like Salix caprea. http://www.plantsystematics.org/imgs/jdelaet/r/Salicaceae_Salix_caprea_12211.html
