Xerochrysum bicolor is a flowering plant in the family Asteraceae, native to Tasmania, where it is found in wetter habitats near the coast. It was originally described by Lindley in 1835 as Helichrysum bicolor,[1] before gaining its current name in 2001.[2]

It is a compact annual or perennial, which normally grows to about 40 cm in height and 50 cm wide, and is usually simple or few-branched. The leaves are lanceolate and range from 2.5 to 10 cm long by 0.3 to 1.4 cm wide. The flowerheads are on stalks and have a diameter of 3 to 4 cm. The inflorescence bracts are papery, the outer ones orange-brown in colour, and the inner ones yellow. It is distinguished from X. bracteatum by its narrower leaves.[3]

The species may be sunk into Xerochrysum bracteatum in a future revision.[3]
