Consider "Three Years She Grew in Sun and Shower" as a Romantic nature poem.
We can describe this poem as a Romantic nature poem because of the close connection that Nature says Lucy has with itself on her death. A key Romantic idea is the way in which nature is something that we can learn from and become united with if we are aware enough of our intimate connection with it. As a child, Lucy, the girl who dies in this poem, has a natural advantage, as Wordsworth believed that children were much more able to respond to the beauty and wisdom of nature and that this became harder as you grew older. Consider the following stanza as an example of the intimate link between Lucy and Nature:
She shall be sportive as the fawn
That wild with glee across the lawn
Or up the mountain springs;
And hers shall be the breathing balm,
And hers the silence and the calm
Of mute insensate things.What is interesting about this poem is that, although Lucy dies, to Nature, this death is actually cast in a very positive light, as Lucy will gain a closeness with nature and become a part of it in such a strong way that it is almost a positive rather than a negative.
