Reddit user Independent-Design17 proposed a fascinating connection between Elden Ring's Erdtree and the Australian Christmas tree, Nuytsia floribunda. While a surface-level resemblance, particularly between the smaller Erdtrees in the game and Nuytsia, is apparent, deeper thematic similarities have captivated fans.

In Elden Ring, the Erdtree guides the souls of the departed, a fact underscored by the game's catacombs situated at its base. Intriguingly, Nuytsia holds a similar spiritual significance in Australian Aboriginal culture, viewed as a "spirit tree" where each flowering branch represents a deceased soul, its vibrant hues echoing the sunset – the believed destination of spirits.

Further strengthening this comparison is Nuytsia's semi-parasitic nature; it draws sustenance from neighboring plants. This mirrors a prevalent fan theory suggesting the Erdtree is parasitic, having overtaken the life-giving roots of an ancient Great Tree. However, it's now understood that game item descriptions referencing a "Great Tree" are mistranslations, actually referring to the Erdtree's own vast root system.

Ultimately, whether these striking parallels to Nuytsia are deliberate design choices by FromSoftware or coincidental remains a mystery known only to the developers.
