Eriostemon australasius commonly known as pink wax flower is a plant in the citrus family Rutaceae and is endemic to eastern Australia.

It is an erect, bushy shrub with narrow oblong leaves and pink flowers with five petals in late winter and early spring.

There are five pink to reddish petals which are about 18 millimetres (0.7 in) long and are covered with similar hairs to those on the leaves, but become smooth with maturity.

[2][3]Eriostemon australasius was first formally described in 1805 by Christiaan Persoon and the description was published in Synopsis plantarum, seu enchiridium botanicum, complectens enumerationem systematicam specierum.

It adapts fairly readily to the garden situation, as long as it has good drainage, in dappled shade to full sun.
