By the DeRosa San Francisco museum, a weeping willow of approximately forty seasons extends graceful, trailing branches. Its unique form captivates observers, a pensive, solitary presence seldom found in this urban landscape. This venerable *Salix babylonica* witnessed the Union Iron Works forging steel ships for distant conflicts. It also saw this very hill escape the devastating 1906 fire, preserving countless Victorian homes. More than a landmark, this leafy elder offers calm contemplation, a silent chronicler of the neighborhood's evolving character, a constant beacon of natural elegance in a dynamic city.
