Celtic Tree Astrology

Celtic tree astrology comes with a horoscope that is said to be based on the spiritual traditions of the ancient Druids.  Now, there are not many historical records about the Druids. A lot of what we hear about them comes from the Romans, who were not big fans.  Although they were not necessarily illiterate, the Druids didn’t think it was a good idea to write down their secrets, and they probably didn't invent the Celtic Tree Zodiac.

Unlike Western zodiac systems, Celtic tree astrology assigns individuals to specific trees.  Each tree symbolizes unique traits, energies, and lessons, and it is an interesting blend of history and reverence for nature. While it is sometimes presented as an ancient system, its actual origins are far more recent.  It was probably crafted in the 20th century as part of the Celtic revival.

This system places people under various tree signs based on their birth dates, much like Western astrology does with the stars. Each tree—like Birch, Rowan, Oak, or Holly—is said to embody certain personality traits and spiritual qualities. The system also includes two “guardian” trees, Holly and Oak.  Holly, associated with nobility and protection, governs the summer solstice and represents the warrior spirit. Oak, ruling the winter solstice, anchors the year with its enduring strength. These trees remind us of the importance of resilience and honor during times of transition.

The Celtic Tree calendar is lunar-based and loosely aligned with the Ogham alphabet, an ancient Irish script that uses tree names as symbols.  It also seems to be heavily influenced by Robert Graves’ fictional work, The White Goddess.  Graves took information from many sources to create a system of tree meanings that may (or may not) be accurate.  

Although it is not supported historically, the Celtic tree astrology is a poetic way to view the human experience. It celebrates diversity, honors the sacredness of nature, and provides an unusual framework for self-discovery. Whether one is considered to be a steadfast Oak, a dreamy Willow, or a visionary Rowan, the trees offer a reminder that we are all part of a living, breathing tapestry woven through time and rooted in the earth.
