Quercus Palustris ‘Green Pillar’

Green Pillar Pin Oak

Quercus palustris ‘Green Pillar’ is a deciduous shade tree with a narrow, columnar habit that remains compact compared to the species. Its strong vertical form makes it an excellent choice for streetscapes, parking lots, narrow residential landscapes, and other locations where space is limited.

The foliage emerges bright green in spring, matures to a glossy dark green during summer, and develops brilliant scarlet, bronze-red, and reddish-brown tones in autumn. In spring, inconspicuous yellow-green flowers appear as male catkins and small female flowers. They are followed by small rounded acorns with shallow caps that mature in the second growing season and provide food for birds and wildlife.

Quercus palustris ‘Green Pillar’ performs best in full sun and moist, acidic, well-drained soils but adapts to a range of soil conditions. Once established, it tolerates urban pollution, heat, and moderate drought, making it a reliable landscape tree for modern urban environments.
