The trees are especially important. They surround her mother's gravesite, and birds sing their beautiful songs in the trees. In the end, they help Sal accept her mother's death. There are three "singing" trees in the novel. The first one is in Kentucky, the second is in the tree outside the hospital in South Dakota, and the third is near her mother's grave in Idaho. They express Sal's powerful reactions to the natural world, but they also respond to her changing emotions. They symbolize the generosity of the natural world, responding to Sal's loss and grief. They may not always sing, but they are always beautiful and are a source of joy for Sal.
Blackberries provide Sal with another memory of her mother. They symbolize the bounty and generosity of nature and Sugar's (Sal's mother) desire to share her love of nature and its goodness with her family. Blackberries are the unexpected sweetness nature gives us, even when we are faced with tragedy and loss.
