Billardiera named after Jacques-Julien de Labillardiere (1755-1834), a 19th century French botanist who visited Western Australia and Tasmania with the D'Entrecasteaux expedition and named many new plant species. Scandens from Latin meaning to climb or sprawl, alluding to its habit.

Scrambling perennial shrub to 3 m tall. Leaves alternate, sessile or shortly petiolate, linear to ovate-lanceolate, to 60 mm long and 15 mm wide; entire or crenate, more or less lobed; upper surface glabrous to scattered-pubescent, lower surface sparsely to densely pubescent. Flowers solitary bell-shaped greenish-yellow to cream appearing between August and December. Fruits are dark green, cylindrical drupe to 40 mm long and 13 mm wide, covered in hairs; green and hard when immature and soft when ripe. Seeds are brown flat reniform seeds to 4 mm long and 2.5 mm wide, covered in wrinkles. Seed embryo type is linear underdeveloped.
Seed collection and propagation
Collect seeds between December and February. Pick mature fruits that are soft or have dark brown seeds inside. Clean ripe fruit as soon as possible as it will go hard if left to dry too long. Rub the fruits in water with your hands to dislodge the seeds from the fruit. Pour the mixture into a sieve to separate the seeds from the flesh. Place the wet seeds in a tray lined with paper and leave to dry for 1 to 2 days. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 85%. This species has physiological dormancy that need to be overcome for the seed to germinate.
