Holly wood is, according to Mr Ollivander, "one of the rarer kinds of wand woods; traditionally considered protective, it works most happily for those who may need help overcoming a tendency to anger and impetuosity. At the same time, holly wands often choose owners who are engaged in some dangerous and often spiritual quest. Holly is one of those woods that varies most dramatically in performance depending on the wand core, and it is a notoriously difficult wood to team with phoenix feather, as the wood's volatility conflicts strangely with the phoenix's detachment. In the unusual event of such a pairing finding its ideal match, however, nothing and nobody should stand in their way."
Harry Potter was chosen by a holly wand.
