(Pin Oak or Swamp Oak)
Quercus palustris is a medium sized, deciduous tree, ideal for parklands, large gardens or avenues. Native to North America, it was introduced to Great Britain in the early 1800s. Its common name is Pin Oak or Swamp Oak.
With a broadly pyramidal crown, this tree grows to around 20m in height - one tree in Hyde Park was recorded as reaching 28m. As it matures, the lower branches begin to droop.
The most notable feature of Quercus palustrisis the unusual foliage which is deeply cut with pointed lobes. In the autumn it turns to fiery russets, reds and oranges.
Quercus palustris adapts to a wide range of soil conditions though will struggle on soils with a high pH. It can cope with moderate drought, urban pollution and has a good tolerance for exposed sites.
Quercus palustris is available from Deepdale Trees as a standard field grown or container grown tree.
