Aslan allowed Digory to take an apple from the new tree back to our world for his ill mother. After she had eaten it, Digory planted the core in his garden, where it grew into a great apple tree. Many years later, the tree was blown down in a storm, and Digory (who was now a professor), had its wood made into the wardrobe that figures in the title of "The Lion, the Witch, and the Wardrobe"—for this wardrobe became the entrance through which the Pevensies would discover Narnia.
