As we mentioned in our "In a Nutshell" section, the youth whom Echo loved – Narcissus – eventually died and became a daffodil. Naturally, there are going to be at least a few flowers in the poem, and at least one daffodil in particular. Only, when Echo mentions the daffodil, it is not a symbol of Narcissus' beauty, but of death (it is "withered "). When you add to that the fact that, earlier in the poem, Echo asks the "herbs and flowers" to "droop," it seems that the flowers in this poem aren't your stock and standard beautiful blooms. Nope, they mean death, and all the grief that comes with it.
