Pinus nigra 'Green Tower' is an evergreen pine grown for its tall, narrowly upright form. Unlike standard Austrian pine, it develops a strong vertical outline with minimal lateral spread, making it suitable for spaces where height is needed without width. The branches are closely set along the trunk and carry long, dark green needles that give the plant a dense, solid appearance throughout the year. Growth is steady rather than fast, and the plant maintains its columnar shape without the need for regular pruning. This variety is best used where vertical structure, screening, or architectural emphasis is required in a restricted footprint.
