In Cormac McCarthy's "Suttree," the imagery of gray vines twisting to the left in the northern hemisphere suggests a unique connection between natural growth and environment. The mention of the dogwhelk's shell hints at how external forces, such as water currents or winds, influence the form and life of living beings. This reflects the idea that all life is shaped by its surroundings.

Additionally, the reference to weeds emerging from cinder and brick illustrates resilience and the ability to thrive in harsh conditions. This juxtaposition of decay and new life symbolizes hope and the continuous struggle for survival, demonstrating that life can flourish even in the most unwelcoming environments.
