Seed collecting:
Collect cones that are matured, turning brown, to ensure mature seed. Be care fully when collecting the cones as the plant is very prickly. Wearing gloves is recommended.
Seed cleaning:
Place the cones in a tray and leave to dry for 2 weeks. Then rub the dried heads with a rubber bung to dislodge the fruits. Use a sieve to separate any unwanted material. Seeds are enclosed in the hard fruit and can be stored as is. Store the fruit with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
