"Tricky customer, eh? Not to worry, we'll find the perfect match here somewhere -- I wonder, now - - yes, why not -- unusual combination -- holly and phoenix feather, eleven inches, nice and supple."
-- Garrick Ollivander (PS5)
After trying out a large number of wands, none of which seem quite right, Harry is handed a holly and phoenix feather wand:
Harry took the wand. He felt a sudden warmth in his fingers. He raised the wand above his head, brought it swishing down through the dusty air and a stream of red and gold sparks shot from the end like a firework, throwing dancing spots of light on to the walls. Hagrid whooped and clapped and Mr. Ollivander cried, “Oh, bravo! Yes, indeed, oh, very good. Well, well, well… how curious… how very curious… “
Harry pays seven Galleons for the wand and leaves the shop.
