English Oak (binomial name Quercus robur) is the type species of the genus (the species by which the oak genus Quercus is defined), and a member of the white oak section Quercus. English oak is indigenous to most of Europe, and to Anatolia to the Caucasus, and also to parts of North Africa.
A wand for good times and bad, this is a friend as loyal as the wizard who deserves it. Wands of English oak demand partners of strength, courage and fidelity. Less well-known is the propensity for owners of English oak wands to have powerful intuition, and, often, an affinity with the magic of the natural world, with the creatures and plants that are necessary to wizardkind for both magic and pleasure.
The oak tree is called King of the Forest from the winter solstice up until the summer solstice, and its wood should only be collected during that time (holly becomes King as the days begin to shorten again, and so holly should only be gathered as the year wanes).
The divide between holly and oak aforementioned is believed to be the origin of the old superstition, “when his wand’s oak and hers is holly, then to marry would be folly,” a superstition that Garrick Ollivander found to be baseless.
Oak trees grow in the Forbidden Forest. In 1992, Rubeus Hagrid pulled Harry Potter and Hermione Granger behind a towering oak when they were serving detention, after he heard an odd noise. A bit later, after he had been paired with Draco Malfoy, Harry spotted a clearing through the tangled branches of an ancient oak.
