Billardiera fusiformis, commonly known as Australian bluebell,[2] is a species of flowering plant in the family Pittosporaceae and is endemic to the south-west of Western Australia.

It is a sturdy, shrubby climber that has linear to narrowly elliptic leaves and blue, white or pink, nodding flowers arranged singly or in groups of up to four.

Flowering occurs in late spring and summer, and the mature fruit is a green, spindle-shaped berry 20–25 mm (0.79–0.98 in) long that turns purplish as it ages.

[9] Australian bluebell was originally endemic to the south-west of Western Australia where it grew in coastal and mallee heath in the Avon Wheatbelt, Coolgardie, Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren bioregions.

[4] It invades woodlands, forests, shrublands, and grasslands, smothering ground flora and small shrubs, with large numbers of seedlings emerging in already infested areas, following fires.
