The idea that the cherry trees are “wearing white for Eastertide” conveys several important things. First, the notion that the trees have dressed up for Easter is an example of personification, that the trees have minds and qualities similar to humans. Second, this personification emphasizes a closeness, or a mutual understanding, between the trees and the speaker; the speaker identifies with the trees. Finally, this closeness emphasizes not only the beauty that the speaker witnesses in the trees, but his ability to see his own life through this experience.
