The Christmas tree (Nuytsia floribunda) is a root hemiparasite tree in the family Loranthaceae, endemic to Western Australia. It is the only member of its family to grow as a full-sized tree rather than an arboreal parasite on other trees, reaching heights of up to ten meters. Nuytsia floribunda is a remarkable botanical curiosity: it parasitizes the roots of a wide range of neighboring plants, extracting water and nutrients while also performing its own photosynthesis. The species is well adapted to the nutrient-poor soils of southwestern Australian woodlands and kwongan heath. Its common name derives from the spectacular mass flowering events that occur in late November and December, when the entire canopy becomes covered in brilliant orange-gold flowers, transforming the landscape around the Christmas period. This is considered one of the most spectacular wildflower displays in Australia. The tree is sacred to several Aboriginal peoples of Western Australia. Nuytsia floribunda is generally considered secure within its native range in southwestern Australia, benefiting from its specialized root-parasitic strategy that allows it to access resources from a broad host community. It is an iconic species of the southwestern Australian flora.
