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.
