What does 'Stargirl' have about a cactus flower?

In "Stargirl" by Jerry Spinelli, the cactus flower symbolizes individuality and beauty in unexpected places. Stargirl, the protagonist, embodies this idea as she embraces her uniqueness in a conformist society. The cactus flower's ability to bloom in harsh conditions parallels Stargirl's resilience and her ability to shine brightly despite facing challenges and rejection from her peers. Ultimately, the flower serves as a metaphor for the importance of self-acceptance and celebrating one’s true self.
