Seed collection and propagation
Collect seeds between January and December. 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. 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. Seeds are non-dormant, viable seed should germinate readily.
