Additional information

Human uses of tree and timberLittle is known about this tree but we could assume that its characteristics are similar to those of the 'parent' trees. Try looking at English oak or sessile oak.
Tree lore and folkloreThe status of this tree is much debated. Some say a natural hybrid in the wild would be rare and the flowering times of the parent trees differ enough to prevent overlap. Others use different reasoning, suggesting that the natural variability in leaves and acorns of either parent means that trees labelled as this hybrid could simply be an odd version of either English or sessile oak.
