Seed collection and propagation
Collect seeds between November and February. Collect maturing fruits, those that are fat and turning grey-purple, by running your hands along the fruit-spikes. Place the fruit in a tray and leave to dry for 1 to 2 weeks. No further cleaning is required if only fruits were collected. If collected with other material, use a sieve to separate the 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. From one collection, the seed viability was average, at 80%.
