Flowering between May and November.

Fruit type:
Greyish-brown woody narrow ovoid fruit to 42  mm long and 12 mm wide, with a sharp pointy end. Fruit split into two to reveal two seeds.
Embryo type:
Investing.
Seed collecting:
Collect mature woody fruit that are greyish-brown and not split. These will contain seeds.
Seed cleaning:
Place the woody fruit in a tray and leave to dry until it split open. Fruits can be placed in the oven at low temperatures to achieve the same result. 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.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
