Plant description

Bushy, branching shrub to 3m tall with green, hairless and finely serrated leaves. Young leaves are hairy and copper coloured. Flowers are creamy in a large ovoid cluster. Flowering occurs all year round. Fruits are large, hairy, woody cones with numerous valves. Seeds are dark brown to black, flat, triangular seed to 10mm long with a large wing around one end. Seed embryo type is investing.

Seed collection and propagation

Collect seeds between January and December. Collect mature cones with obvious un-open valves. These will contain viable seeds. Place the cones in a tray and leave to dry until the valves open. Alternatively, place the cones in an oven at low temperatures to speed up the process. Then place the dried cones in a bucket and shake to dislodge the seeds from the valves. Separate the seeds from the fruit and 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 80%. Seeds are non-dormant, viable seed should germinate readily.
