There is something about the weeping willow that strikes us universally. The branches that sweep downward, the leaves that brush the water, the form that seems like petrified weeping — it is impossible to look at a weeping willow without feeling something that is hard to name. It is no accident that nearly every human culture that knows it has attributed profound meaning to it.

The weeping willow: botany and origins

The weeping willow (Salix babylonica) originates from northern China, from where it was introduced to Europe in the eighteenth century. The species name — babylonica — comes from a mistake by Linnaeus, who believed that the willow mentioned in Psalm 137 ("By the rivers of Babylon we hung our harps upon the willows") was this tree; in reality the psalm likely refers to poplars. It is a fast-growing tree (up to 25 meters in height), with long, flexible, drooping branches that reach the ground or water surface. The native Italian willows — the white willow (Salix alba), the purple willow (Salix purpurea), the crack willow (Salix fragilis) — are not drooping, but live along rivers and in riparian forests, where they play a fundamental ecological role as bank stabilizers and habitat for numerous animal species.

The willow in Chinese tradition: immortality and spring

In China, where the weeping willow is native and common, its symbolic meaning is opposite to that in the West: it is not a tree of mourning but of immortality and spring. The branches of willow that sprout so early in February and March — among the very first trees to dress in green — are considered symbols of vitality, rebirth, and good fortune. During the Qingming Festival (the Chinese day of the dead, in April), willow branches are hung on the doors of houses and carried as protection against evil spirits. The classical Chinese painter uses the willow as a recurring motif in poetry and painting: the ink that depicts drooping branches over a boat on the river is one of the most classic subjects of Chinese landscape painting from the Song and Ming dynasties.

The willow in European culture: mourning, abandonment, and Romantic poetry

In Europe, the weeping willow has acquired a predominantly melancholic connotation. Shakespeare uses it in Othello (Desdemona's willow song), in Hamlet (Ophelia dies falling from a willow bending over water), in The Merchant of Venice. In all cases the willow is associated with romantic abandonment, mourning, and premature death. Romantic European painting uses the willow as a landscape element that evokes melancholy: Turner, Constable, Friedrich paint landscapes where the weeping willow accompanies scenes of death, mourning, or separation. In Victorian and Romantic cemeteries in Italy (Milan's Monumental Cemetery, Bologna's Certosa, Campo Verano cemetery in Rome), weeping willows were planted systematically to create an atmosphere of melancholic contemplation. This tradition has persisted: the weeping willow remains one of the most common trees in Italian cemeteries today.

The willow in medicine and pharmacology

The bark of the willow (especially the white willow, Salix alba) contains salicin, a glycoside that the body metabolizes into salicylic acid — the natural ancestor of aspirin. The use of willow bark as an analgesic and antipyretic is documented as far back as ancient Egypt (Ebers papyrus, ~1550 BCE), in Greek Hippocratic medicine, and in traditional Chinese medicine. In 1897, chemist Felix Hoffmann of Bayer synthesized acetylsalicylic acid — aspirin — from the natural salicin in willow bark, creating the most consumed drug of the twentieth century. The weeping willow you see in the park is literally the ancestor of the aspirin you keep in your medicine cabinet.

How to use the willow in landscape and garden

• Plant the white willow near water: the white willow (Salix alba) is the native Italian species best suited for planting in gardens with ponds, along streams, or near watercourses. It grows extremely fast (1-2 meters per year) and forms a majestic tree in just a few years. Its roots stabilize banks without damaging them with the same efficiency as artificial structures.
• Twigs as building material: the flexible branches of willows (Salix viminalis, the basket willow) are one of Europe's oldest weaving materials. Basketry, pergolas, woven living hedges — all traditional techniques that use green willow. Even children can learn to build small structures with fresh willow branches: just place green branches from a willow in a glass of water to create extremely flexible and easy-to-work material.
• Willow bark tea: dried white willow bark (Salix alba) is available at herbalists. Willow bark tea is used as a natural analgesic for headaches and joint pain. It should not be used during pregnancy, by those allergic to aspirin, or alongside anticoagulants. The active ingredient is the same salicin that led to the invention of aspirin.
• With children — the willow wand: the thin, flexible branches of willow have been used for centuries as dowsing rods (to find water), as magic wands in fairy tales, as primitive musical instruments. With a small knife (for adults), you can carve simple whistles from willow branches: make a circular incision, soften the bark by tapping with the knife handle, slide off the bark cylinder, carve the holes — and play. It is a traditional activity of Italian rural craftsmanship that very few children know anymore.
• Visit natural willow beds: the natural willow beds along the Po and Arno rivers are very important ecosystems for biodiversity — they host numerous bird species (nightingale, reed warbler, hemp finch, penduline tit), amphibians, reptiles, and invertebrates. In spring, the catkins of white willows are one of the first sources of pollen for bees just emerging from winter dormancy.

The weeping willow carries within it one of the richest cultural histories of any tree: from Chinese immortality to European Romantic mourning, from Hippocratic medicine to modern aspirin, from traditional basketry to the figure of Ophelia. It is a tree that does not need to be large or rare to be profound. It only needs a watercourse and someone who stops to watch its branches reflected in the water for a moment.
