There are several themes apparent in "The Flowers" by Alice Walker. A prominent one is a loss of childhood innocence, which a previous Educator response explains.
An additional theme is that violence and racism have a ripple effect, touching generation after generation.
The man whom Myop finds is a victim of racist violence, as evidenced by the details readers are provided in the setting. Myop's family members are sharecroppers, and it is noted that she has a "dark brown" hand. The man she finds "had been...tall," and he wore denim overalls, most of which have rotted away. He has not only been hanged, as evidenced by the noose, but has also been beheaded.
Myop's grotesque discovery shows that the violence of adults will eventually reach the younger generations. But there is also, in the ending, hope that generations who follow in the footsteps of violence will be able to create something beautiful from the ruins. After all, Myop discovers a "wild pink rose" growing near the skull and adds it to her bouquet of flowers. She eventually lays down this bundle, perhaps as an offering of beauty to counter an act of such ugliness. Myop's gesture shows that even in acts of violence, younger generations often provide hope of a more beautiful future.
