Plant description

Fruits are clusters of golden brown ellipsoid capsules with numerous seeds. Seeds are tiny orange-red ellipsoid seed to 0.4 mm long and 0.2 mm wide, with fine reticulated surface. Seed embryo type is broad.

Seed collection and propagation

Collect seeds during October. Collect fruits either by picking off the mature heads, those turning brown and come-off easily or break-off the whole spikes. Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Be careful, as the seeds are very small. Seeds are brown and hard. 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 high, at 100%.
