Corymbia ficifolia, commonly known as red flowering gum,[2] is a species of small tree that is endemic to the south-west of Western Australia.

[citation needed] Red-flowering gum was first formally described in 1860 by Ferdinand von Mueller, who gave it the name Eucalyptus ficifolia and published the description in his book, Fragmenta Phytographiae Australiae.

[2] Corymbia ficifolia grows in sandy soil in low forest on slopes and is restricted to a sub-coastal distribution south-east of Perth, east of Mount Frankland, Walpole and the Stirling Range.

[12] In nature Corymbia ficifolia prefers infertile, sandy soils but it is readily adaptable to most temperate locations, provided it is not exposed to severe frost or sustained tropical damp.

The largest known single-stemmed tree of this species in the world (216.5 cm diameter) is located on Princes Street in Hamilton, New Zealand.

[13] Because of its big and lovely colourful flowers, genetic improvement for cold resistance in Dublin area in Ireland is being carried out by collecting seeds in the coldest parts of Western and Southern Australia where it grows.
