Waitzia acuminata, commonly known as orange immortelle, is an annual forb in the family Asteraceae.

[3] Waitzia Acuminata occurs in all mainland states of Australia and is currently not considered rare or endangered.

[5] The species was first formally described in 1845 by German botanist Joachim Steetz in Plantae Preissianae.

[1] Two varieties are currently recognised: Waitzia acuminata steetz can grow up to 600 mm high and has reddish stems.

Waitzia acuminata grows in sand dunes and rocky outcrops, favouring warmer climates[10] and areas with high sun exposure.

[11] Prior studies suggest environments with increased exotic grasses may have decreased abundance of Waitzia acuminata.

[12] Due to its aesthetics Waitzia acuminata is used in as an ornamental garden plant across parts of Australia.
