Description:
Quercus palustris 'Pringreen' Green Pillar® is a deciduous, columnar tree known for its strong central leader and vertical side branches. This cultivar is particularly valued for its narrow, upright form, making it ideal for urban landscapes and areas with limited space.

Flowers:
In spring, Green Pillar® produces inconspicuous yellowish-green flowers in separate male and female catkins as the leaves emerge. These flowers are not significant for ornamental value but are essential for the tree's reproductive cycle.

Foliage:
The tree features glossy, dark green leaves up to 15 cm long with five to seven deep, fine lobes. In autumn, the foliage turns deep red to bronze, providing a vibrant seasonal display.

Fruit:
Following the flowering period, the tree can produce small, rounded acorns with a shallow, saucer-shaped cap. These acorns mature in autumn and provide food for wildlife.

Form and Size:
Green Pillar® has a narrowly columnar habit with dense, uniform, upright branching and a central leader. It typically reaches a height of 14 meters and a width of 3 meters, making it suitable for various landscape applications, including small gardens and urban settings.

Growing Conditions:
This oak thrives in full sun and prefers moist, well-drained, fertile soil. It is adaptable to a range of soil types, including clay and loamy soils, and exhibits good drought tolerance once established. Regular watering during dry periods will promote optimal growth and flowering.

Uses:
Green Pillar® is ideal for use in all garden situations, as an avenue, along a fence line, or to bring vertical lines into gardens and open spaces. Its narrow form makes it an exceptional choice for those tight on lateral space.

Maintenance:
The tree is relatively low-maintenance, with strong branch angles and an upright growth habit that minimize the need for pruning. If pruning is necessary, it should be done in late winter to avoid exposing fresh cuts to potential pathogens.
