Pin Oak bark

Belongs to the red oak section and closely resembles the Scarlet Oak or Quercus Coccinea. Its straight central leader, pollution tolerance and ease of transplanting make the Pin Oak ideal for the urban landscape. A unique, vertically radial branching direction occurs on older trees.

Pin Oak leaves

The Pin Oak tolerates a variety of soil conditions but prefers moist to wet ground reflecting its native lowlands habitat in Niagara and the eastern United States. Soil with an acidic ph is required. Ferric ammonium citrate may be added as a last resort to non-acidic soil.


Shinny, dark-green leaves with potential for nice red, yellow or brown fall colour. Lobes are pointy with lots of space between them. 5-7 lobes per leaf.
