Quercus palustris Green Pillar ('Pringreen')
upright pin oak
This special form of Quercus palustris has an elegant neat and slender upright habit. The deeply lobed shiny green leaves emerge in spring giving the tree a smart green coat for the summer before turning a rich scarlet in autumn. Neater in habit and with more predictable autumn colour than other fastigiate oaks, this variety would make a stunning avenue tree or specimen tree where space is limited.
Please note: The decorative pot shown is not included and is for presentation purposes only. Our trees are supplied in standard nursery pots, and the images showing young trees in pots are intended to give an idea of our larger plant’s height and form on arrival. We do offer a wide range of decorative pots separately if you’d like to recreate the look, although for long-term success, trees are best planted in the ground.

How to care for Quercus palustris Green Pillar ('Pringreen'):
Plant in deep, fertile, well-drained soil in a sunny position, avoiding areas prone to waterlogging. When planting, incorporate organic matter into the backfill and firm the soil gently around the roots. Water well after planting and throughout dry periods until well established, typically within the first two to three years.
Young trees benefit from staking to prevent wind rock; use a sturdy stake and soft tie, positioning it low to allow natural trunk movement and remove once the tree is stable. Prune in late winter or midsummer to avoid sap bleeding, removing any dead, diseased, or poorly placed branches to create a strong framework.
As the tree matures, minimal pruning is needed beyond occasional maintenance. Each spring, mulch around the base with compost or leaf mould to retain moisture and improve soil structure.
