Reddit user Independent-Design17 proposed a fascinating connection between Elden Ring's Erdtree and the Australian Christmas tree, Nuytsia floribunda. Superficial similarities exist, particularly when comparing the in-game Small Erdtrees to Nuytsia. However, the parallels run deeper.

In Elden Ring lore, the Erdtree guides the souls of the departed, explaining the catacombs at its base. Intriguingly, Nuytsia holds similar spiritual significance in Australian Aboriginal culture. Its vibrant blooms represent the souls of the deceased, their bright colors echoing the sunset – the perceived destination of spirits.

Further strengthening this connection is Nuytsia's semi-parasitic nature; it draws nutrients from neighboring plants. This mirrors a popular fan theory suggesting the Erdtree is parasitic, having usurped the life force of an ancient Great Tree. However, game text referencing a "Great Tree" is now understood to be a translation inaccuracy, referring instead to the Erdtree's own extensive root system.

Ultimately, whether FromSoftware intentionally drew inspiration from Nuytsia floribunda remains a mystery, known only to the developers.
