Billardiera variifolia is a species of flowering plant in the family Pittosporaceae and is endemic to the southwest of Western Australia.

It is a twining shrub or climber with elliptic adult leaves and groups of deep purple flowers that fade to blue as they age.

Billardiera variifolia is twining shrub or climber that typically grows to a height of up to 2.5 m (8 ft 2 in) and has both seedling, intermediate and adult leaves on the same plant.

Flowering occurs in from October to December or from January to May and the mature fruit is a spindle-shaped berry 20–24 mm (0.79–0.94 in) long.

[2][3] Billardiera variifolia was formally described in 1824 by Augustin Pyramus de Candolle in his Prodromus Systematis Naturalis Regni Vegetabilis.
