Quercus palustris Pringreen Green Pillar®

Common Name: Green Pillar® Pin Oak

Description:
Quercus palustris 'Pringreen' Green Pillar® is a striking, columnar selection of the Pin Oak, valued for its narrow, upright growth habit and stunning seasonal colour changes. Its deeply lobed, glossy green leaves create a dense, vertical canopy that turns vibrant shades of red and orange in autumn, making it a standout feature in any landscape. This deciduous tree is well-suited to Melbourne’s climate, thriving in full sun with well-drained soil and tolerating urban conditions, including pollution and compacted soils. Green Pillar® is an excellent choice for narrow spaces, avenue planting, screening, or as a dramatic feature tree in modern landscapes. Its structured form requires little maintenance, and it is drought-tolerant once established.
