Betula 'Fastigiata Joes'Betula 'Fastigiata', also known as Upright Birch is a towering tree noted for its beautiful bark which grows almost pure white with some of it breaking and cracking with age, creating contrasting black cracks among the patches of white bark. The bark turns to a hue of silver grey as the tree matures, its columnar growth allowing for a tall, branching crown that tends to twist and twine as it grows ever taller with some known to reach above 12 meters.
