Green Pillar is a columnar version of the classic Pin Oak, offering all the character and fall drama of pin oak in a much narrower silhouette. If you love bold, upright trees but don’t have much horizontal space, this tree delivers. Dark green, glossy leaves turn fiery red or scarlet in autumn for a showstopping fall display. Each spring it produces green catkins that mature into small, oval acorns. As it grows, it maintains a strong central leader and vertical branching, making it ideal for tight yards, urban lots, streets, or any site where you want height without spread.
Plant in full sun in moist, acidic, well-drained soil. Water regularly during establishment, mulch to keep roots cool and moist, and prune lightly to maintain strong structure. Once established, it is a hardy, low-maintenance tree with excellent fall color.
