Seeds are three-sided brown seed to 2 mm long and 1 mm wide with dense tuberculate surface. Seed embryo type is spatulate.
Seed collection and propagation
Collect seeds between January and April. Collect heads that are matured, greyish-white, a bit spongy and contain brown seeds. Place the heads in a tray for one to two week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a sieve to separate any unwanted material. Viable seeds will be small and brown. 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. Seeds are non-dormant, viable seed should germinate readily.
