Plant description

Prostrate mat-forming shrub to 40cm across. Leaves linear, narrow-elliptic or oblanceolate to 18 mm long and 3 mm wide; thin, striate-veined on lower surface; apex often recurved. Flowers solitary, or rarely 2-3, corolla tube cylindrical, bright-red, to 12 mm long, densely bearded inside except at the tip. Flowering between June and November. Fruits are dark-green to purple globular drupe. Seeds are brown, woody ellipsoid seed to 6 mm long and 4 mm wide. Seed embryo type is linear, underdeveloped.

Seed collection and propagation

Collect seeds between November and March. Collect ripe drupes, those that are fat and turning purple. Fruits may also be gathered from the ground under the foliage. Remove unwanted material from the seed collection, leaving only fruits. Place fruits in a bucket of water and leave to soak over night. Then rub the fruit to remove the flesh. Rub and change the water a few times until all the fresh are removed. Leave the cleaned seed to dry and then store 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 92%. This species has morphophysiological dormancy and is difficult to germinate
