Australian Christmas Tree
The habit of the species is a tree up to 10 metres (33 ft) high, or as a shrub. The rough bark is grey-brown. Flowers are a vivid yellow-orange, appearing between October and January.
It is a root hemiparasite, is photosynthetic and mainly obtains water and mineral nutrients from its hosts. The haustoria arising from the roots of Nuytsia attach themselves to roots of many nearby plants and draw water and therefore nutrients from them. Almost all species are susceptible to attack; haustoria have even been found attached to underground cables. In natural settings Nuytsia withdraws relatively little from each individual host, but is attached to so many other plants that the benefit to this hemiparasitic tree is likely to be considerable.
Nuytsia floribunda is well known in Southwest Australia, where it is named the Christmas tree, the common name outside of this region is Western Australian Christmas tree. The appearance of abundant flowers in summer is a spectacular display. Although Nuytsia seeds germinate readily and seedlings are easy to grow for a year or two, cultivation of the species to maturity is regarded as difficult, with little success outside of its native habitat. It appears on a variety of soil types throughout Southwest Australia, the distribution of the species extends to the east of the Esperance Plain and to the north on the Geraldton Sandplains.
