People put bottles on trees to ward off evil spirits, a tradition that traces back over a thousand years to Central and West Africa. What started as a deeply spiritual practice has evolved into one of the most recognizable pieces of folk art in the American South, where colorful glass bottles on bare branches are a common sight in gardens and front yards.
The African Origins of Bottle Trees
The tradition dates to at least the 9th century A.D. among the Bakongo people, whose homeland sits near the mouth of the Congo River. Art historian Robert Farris Thompson traced the practice to this region, where multiple ethnic and cultural groups shared a similar belief: that empty vessels hung outside a home could catch malicious spirits and prevent them from entering.
Before glass bottles were widely available, people used hollow gourds. The idea likely started with a simple observation. Wind blowing across the opening of a bottle or gourd creates an eerie, moaning sound. Stories began circulating that spirits lived inside the vessels, and the practice of deliberately placing empties near doorways grew from there. In the broader West African tradition, the tree itself carried symbolic weight as a representation of the unending circle of life.
How the Spirit Trap Was Supposed to Work
The folklore follows a satisfying logic. Malevolent spirits roaming at night would be drawn to the bottles and enter them, becoming trapped by what was described as an “encircling charm.” Come morning, the rising sun would burn the spirits up, destroying them. The bottles acted as a nightly reset, catching whatever dark energy drifted by and neutralizing it by dawn. This is why the bottles were always placed outside but close to the home, functioning as a kind of spiritual perimeter defense.
From Africa to the American South
The tradition crossed the Atlantic with enslaved people from the Congo region. In America, the heavy gourds that had been used in Africa were harder to come by, so glass bottles became the natural substitute. The practice took deep root in the rural South, where bottle trees became folk symbols closely tied to the communities that created them.
The most traditional version uses a dead crepe myrtle, a quintessential Southern plant, with bottles pushed onto the cut ends of its branches. Crepe myrtles work well because their naturally twisting, multi-branched form creates plenty of points to hold bottles at different angles. Cedar trees and simple wooden poles with nails or dowels are also common bases.
Why Blue Bottles Are Preferred
While bottle trees can feature any color of glass, cobalt blue became the overwhelmingly favored choice. In African spiritual tradition, blue is the color associated with the spirit or life force. That symbolism carried into the Southern practice, where blue was considered especially effective at attracting and trapping nighttime spirits.
This connection runs parallel to another Southern tradition: “haint blue,” the soft blue-green paint applied to porch ceilings across the region to keep ghosts (or “haints”) away. Paint companies sell haint blue as a specific shade, but bottle tree enthusiasts say it’s more of a concept than a single color, one that can apply to many shades of blue. For decades, the most popular bottles for the purpose were old cobalt blue milk of magnesia bottles, which were cheap, plentiful, and exactly the right color.
Bottle Trees as Modern Garden Art
Starting in the late 20th century, bottle trees moved from rural folk tradition to mainstream garden art. Mississippi garden writer Felder Rushing became one of the most prominent champions of the practice after encountering his first bottle tree at age 16. His garden in Fondren, a neighborhood in Jackson, Mississippi, eventually grew to include over a dozen bottle trees, and the neighborhood itself became home to more than a hundred of them, what Rushing has called “the densest concentration in the known universe.”
Today bottle trees show up in gardens across the entire country, not just the South. Many people who build them have no connection to the original spiritual tradition and simply enjoy the way colored glass catches sunlight. Garden centers sell purpose-built metal “trees” with curved branches designed to hold wine bottles. Others prefer the traditional approach: a weathered piece of wood with real branches, dressed in whatever bottles they’ve collected. The result is the same either way. On a bright afternoon, a bottle tree throws jewel-toned light across a yard in a way that few other pieces of garden art can match.
Whether someone builds a bottle tree to honor a centuries-old spiritual practice or just because they like the way green wine bottles look in the sun, the tradition carries a remarkable unbroken line from 9th-century Central Africa through the American South and into suburban gardens nationwide.
