 Despite its deceptive simplicity in rhyme and meter , " Trees " is notable for its use of personification and anthropomorphic imagery : the tree of the poem , which Kilmer depicts as female , is depicted as pressing its mouth to the Earth 's breast , looking at God , and raising its " leafy arms " to pray . The tree of the poem also has human physical attributes — it has a " hungry mouth " , arms , hair ( in which robins nest ) , and a <unk> .
