Seed collection and propagation
Collect seeds between January and December. Pick heads that are maturing, drying off, with brown seeds that dislodge easily. Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads by hand to dislodge the seeds. 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. Seed viability can be average. This species has physiological dormancy that need to be overcome for the seed to germinate.
