What is the symbolism of the palm tree in the poem, The Harlem Dancer?

The palm tree symbolizes strength but, at the same time, constraint. The speaker compares the dancer’s body and demeanor to a palm tree. Specifically, “she seemed a proudly-swaying palm” (7). This description imparts a semblance of dignity onto the dancer, for she is proud and towers over the crowd. Generally associated with strength, the image of the tree gives the dancer an air of authority and grace. However, trees are also rooted and cannot move of their own accord, suggesting that the dancer also does not have complete control over her own life.
