Seed collection and propagation
Collect seeds between December and January. Collect whole plant that are starting to dry off and turning pale straw colour. Place the plant material in a tray for 1-2 week to dry. Then rub the pods with your hands or a rubber bung to dislodge the seeds. Pass the material through a sieve to separate the unwanted material. The finer material will contain both seeds (soft) and frass (hard) usually distinguishable from each other. With finer sieves, the seeds can be separated from the frass but this is not essential for storage or propagation. 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 is usually high.
