What does the symbol Bean Trees reveal?

“Bean,” Turtle’s first word, symbolizes the promise that, like a dried-up seed that grows, a mistreated woman may thrive if given enough care. The bean trees, another name for the wisteria vine that Turtle spots in Dog Doo Park, symbolize transformation, a spot of life in the midst of barrenness. The bean trees have a symbiotic relationship with bugs called rhizobia, which move up and down the wisteria vine’s roots and provide a network that transfers nutrients. This mutual aid symbolizes the help and love human beings give one another. The bean trees, like people, only thrive with a network of support.
