I know it's native to America, but plant 3 of these in a row in front of a picture window, watch them sway in the breeze on a cold winter's day while listening to the song Somewhere My Love, and the sheer beauty of the scene will make you experience a little slice of Heaven deep in the Russian forest. Some trees give you auras of romance everytime you see them, this tree is one of them.
