Black Oak - Quercus velutina
Black Oak trees are shade and competition intolerant and often found on dry, sandy soils. White-tailed deer, birds and other mammals help to disperse the seeds of this native Oak. The inner bark contains a yellow pigment called quercitron which was a popular dye in the 1940s.
Black Oaks can grow up to 20 m high with their trunks reaching almost 1 m in diameter. Photo by Shelley Hunt.
Black Oak buds are 6-8 mm long and distinctly angled. Photo by Jesse Wolf.
The bark is dark grey and becomes darker with age, with deeply furrowed rounded ridges. Photo by Shelley Hunt.
