The willow tree’s association with the moon comes from the lunar influence on water, including tides. Fast-growing and long-lived, the weeping willow is ubiquitous in cemeteries, where its drooping shape is reminiscent of a grieving human. The willow’s regenerative properties, associated with everlasting life, mean that it can be reproduced by planting a twig in moist soil. The willow is associated with renewal, growth, vitality and immortality in countries from England to China. The Christian connection between death and willows is thought to originate with Psalm 137, which refers to willow trees and grief.
