Flowering between August and October. Fruits obovoid to 4 mm long, covered in grey hairs. Seed embryo type is spatulate.
Seed collection and propagation
Collect seeds between September and December. Collect maturing fruits, those that are fat and contain hard seeds inside. Collecting good mature fruits will be time consuming as few fruits may be produced. Place the fruit in a tray and leave to dry for two weeks. Then rub the fruits gently with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. 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 This species tends to produce very few viable seeds.
