It reaches around 14 metres tall but holds to roughly 3 metres wide, which is the entire point of the tree: it gives you the scale, shade and autumn colour of an oak in a footprint that a standard Pin Oak could never fit into.\u003c\/p\u003e\n\u003cp\u003eThe glossy dark green lobed foliage turns through bronze to deep red in autumn before dropping, leaving a tidy upright branch framework through winter. Growth is upright and naturally even, so a planted row grows up matched without shaping.\u003c\/p\u003e\n\u003cp\u003eIt wants full sun and adapts to a wide range of soils, including heavier ground and sites that hold moisture for short periods, which is characteristic of Pin Oak. Frost hardy, wind firm and tolerant of urban conditions once established.\u003c\/p\u003e\n\u003cp\u003eSpecified for driveways, narrow verges, car park rows, tight streetscapes and avenue planting between buildings, and useful as a strong vertical feature in a garden where a spreading oak would take the whole space.\u003c\/p\u003e\n\u003cdiv style=\"background:rgba(128,128,128,0.10);padding:26px 28px;margin:32px 0;\"\u003e\n\u003cp style=\"margin:0 0 14px;line-height:1.7;color:currentColor;\"\u003e\u003cstrong\u003eAlso sold as:\u003c\/strong\u003e Green Pillar Pin Oak, Green Pillar® Oak, Upright Pin Oak, and \u003cem\u003eQuercus palustris\u003c\/em\u003e 'Pringreen'.

It carries the same glossy lobed foliage and deep red autumn colour as the species but holds a narrow upright form, reaching around 14 metres tall and only about 3 metres wide.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"border-bottom:1px solid rgba(128,128,128,0.25);padding:18px 0;\"\u003e\u003csummary style=\"font-weight:500;cursor:pointer;line-height:1.4;padding-right:12px;font-size:16px;color:currentColor;\"\u003eIs 'Pringreen' the same tree as Green Pillar?\u003c\/summary\u003e\u003cp style=\"margin:14px 0 0;line-height:1.7;color:currentColor;opacity:0.85;\"\u003eYes. 'Pringreen' is the registered cultivar name and Green Pillar is the trade name it is sold under, so Quercus palustris 'Pringreen' and Green Pillar Pin Oak are the same tree.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"border-bottom:1px solid rgba(128,128,128,0.25);padding:18px 0;\"\u003e\u003csummary style=\"font-weight:500;cursor:pointer;line-height:1.4;padding-right:12px;font-size:16px;color:currentColor;\"\u003eHow is it different from a standard Pin Oak?\u003c\/summary\u003e\u003cp style=\"margin:14px 0 0;line-height:1.7;color:currentColor;opacity:0.85;\"\u003eWidth. A standard Pin Oak develops a broad pyramidal canopy and needs open ground. Green Pillar holds to about 3 metres wide at a similar height, so it fits driveways, narrow verges and planting between buildings where the species would be unusable. Foliage, autumn colour and hardiness are the same.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"border-bottom:1px solid rgba(128,128,128,0.25);padding:18px 0;\"\u003e\u003csummary style=\"font-weight:500;cursor:pointer;line-height:1.4;padding-right:12px;font-size:16px;color:currentColor;\"\u003eHow big does Green Pillar grow?\u003c\/summary\u003e\u003cp style=\"margin:14px 0 0;line-height:1.7;color:currentColor;opacity:0.85;\"\u003eAround 14 metres tall by 3 metres wide at maturity, which takes several decades. Plan for the height rather than the width, and keep it clear of overhead powerlines even though the footprint at ground level is small.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"border-bottom:1px solid rgba(128,128,128,0.25);padding:18px 0;\"\u003e\u003csummary style=\"font-weight:500;cursor:pointer;line-height:1.4;padding-right:12px;font-size:16px;color:currentColor;\"\u003eWhen does it colour in autumn?\u003c\/summary\u003e\u003cp style=\"margin:14px 0 0;line-height:1.7;color:currentColor;opacity:0.85;\"\u003eThrough autumn the glossy green foliage moves through bronze into deep red before dropping. Cool nights and a bright, dry autumn give the strongest colour, while a mild humid autumn produces a softer and shorter display.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"border-bottom:1px solid rgba(128,128,128,0.25);padding:18px 0;\"\u003e\u003csummary style=\"font-weight:500;cursor:pointer;line-height:1.4;padding-right:12px;font-size:16px;color:currentColor;\"\u003eIs it suitable for a driveway or narrow verge?\u003c\/summary\u003e\u003cp style=\"margin:14px 0 0;line-height:1.7;color:currentColor;opacity:0.85;\"\u003eThis is exactly what it was selected for. The narrow crown keeps clear of vehicles and buildings, the even upright habit means a planted row matches up, and the trunk can be lifted for clearance. Still allow proper soil volume for the roots, and keep it well clear of underground services.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"border-bottom:1px solid rgba(128,128,128,0.25);padding:18px 0;\"\u003e\u003csummary style=\"font-weight:500;cursor:pointer;line-height:1.4;padding-right:12px;font-size:16px;color:currentColor;\"\u003eHow far apart should Green Pillar be planted?\u003c\/summary\u003e\u003cp style=\"margin:14px 0 0;line-height:1.7;color:currentColor;opacity:0.85;\"\u003ePlant 3 to 4 metres apart for a tight avenue or driveway row, or 4 to 5 metres for individual trees that read separately.

It drops its leaves through late autumn and stands bare over winter, revealing a tidy upright branch framework, then leafs out again in spring. Young pin oaks sometimes hold dry brown leaves through part of winter, which is normal and passes with age.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"border-bottom:1px solid rgba(128,128,128,0.25);padding:18px 0;\"\u003e\u003csummary style=\"font-weight:500;cursor:pointer;line-height:1.4;padding-right:12px;font-size:16px;color:currentColor;\"\u003eHow do I care for it?\u003c\/summary\u003e\u003cp style=\"margin:14px 0 0;line-height:1.7;color:currentColor;opacity:0.85;\"\u003eWater deeply through the first three summers, mulch widely and keep turf off the root zone while it establishes. Prune only in late winter, removing damaged wood and lifting the lower branches gradually to the clearance you want. Do not attempt to reduce the height, as topping ruins the form.\u003c\/p\u003e\u003c\/details\u003e\n\u003c\/div\u003e","brand":"Evergreen Trees Direct","offers":[{"title":"100L","offer_id":47079606845639,"sku":"QUEPALPRI100L","price":700.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4945\/4279\/files\/QUERCUSPRINGREEN100L.png?v=1788419339","url":"https:\/\/www.evergreentrees.com.au\/products\/quercus-palustris-pringreen-green-pillar-upright-pin-oak","provider":"Evergreen Trees Direct","version":"1.0","type":"link"}
