Help in identifying a tree




Please help me in identifying the tree in the attached picture.


Lina,  This is a bit more difficult to pinpoint exactly because the picture is a bit fuzzy…but it looks like a willow cultivar.  Without a close up of the leaf I am just taking a guess at the cultivar…if the foliage emerges pinky in colour and matures to a creamy white and green, my best guess is Salix xIntegra Hakuro Nishiki…a Hakuro Nishiki Dappled Willow .  The other likely candidate is the Salix matsudana, or Corkscrew Willow
