Flowering between September and December. Fruits are red-brown woody narrow ovoid fruit to 28 mm long, often pubescent. Fruit splits into two to reveal two seeds. Seeds are brown ovoid seed to 8 mm long and 5 mm wide (25 mm long and 7 mm wide including the wing that extend narrowly down both sides of seed). Seed embryo type is investing.
Seed collection and propagation
Collect seeds between December and March. Collect mature woody fruit that are brown and not split. These will contain seeds. Place the woody fruit in a tray and leave to dry until it split open. Place the dried fruit in a bucket and shake to dislodge the seeds from the valves. Separate the seeds from the fruit and 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 average, at 75%. Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
