Betula pendula 'Youngii' (Youngii European White Birch)
Michael's Opinion
This peculiar tree has very pendulous branches and can be quite interesting or attractive, depending on how it takes shape. Attempt to train its weeping habit for maximum effect. The trunk becomes undesirably noticeable over time, though. A good choice for a specimen or accent tree or shrub.
