Wand wood

Various different types of wood are used in the construction of wands. They are also embedded with a core of a magical substance. Wands vary according to length, from at least 7" to 16", as well as rigidity, ranging from "springy" to "unyielding".

Author's Comments
J. K. Rowling has explained her choice of wand woods for Harry Potter and Lord Voldemort:


 * "It was not an arbitrary decision: holly has certain connotations that were perfect for Harry, particularly when contrasted with the traditional associations of yew, from which Voldemort’s wand is made. European tradition has it that the holly tree (the name comes from ‘holy’) repels evil, while yew, which can achieve astonishing longevity (there are British yew trees over two thousand years old), can symbolise both death and resurrection; the sap is also poisonous."

Rowling has also revealed that she discovered that Harry's wand wood corresponded to his date of birth in the Celtic tree calendar afterwards, and decided to use the calendar to assign the wand woods of Ron Weasley and Hermione Granger as a "hidden connection" between the three.

Behind the scenes

 * Other woods in the Celtic tree calender include birch, rowan, alder, hazel, ivy, and reed, thus these may be other wand woods.
 * Although J. K. Rowling has said that she "only used the Celtic assignations for Ron and Hermione", Draco Malfoy's wand wood of hawthorn matches his date of birth in the Celtic tree calendar as well.
