Propagation
Collect and sow fresh seeds in a well-drained media and keep moist.  Up to 80% od seeds germinate within 30 days and should be picked out and pot up, then grown on for one season with protection from hot sun before planting out.

Note:
Young trees are pyramidal in outline and mature trees shed the lower branches are generally umbrella-shape. The creamy yellowish timber is soft and is used for plywood, studs, structural beams and as pulp wood. It was extensively logged for shipbuilding during the 1800's.
The edible seeds (pinhao) are excessively harvested in southern Brazil with over 3,400 tonnes collected annually and are boiled and consumed as a snack. The combination of seed collection and extensive logging seriously threatens the regeneration of the species.

Botanic information
Leaf: The sessile glossy dark to mid-green leathery textured lanceolate to oblong-lanceolate leaves are up to 60 mm (2⅜ in) long by 12 mm (½ in) wide and taper to a pungent acuminate apex with sharp margins. They are arranged spirally and loosely overlapping towards the end of the sterile branches with stomata on the upper surface and the underside is keeled. The leaves on fertile branches are shorter and more densely arranged with prominent stomata on the underside.

Flower: The dense cylindrical male cones are up to 200 mm (7¾ in) long by 30 mm (1⅛ in) wide and has imbricate scales. The globular chestnut-brown female cone is up to 250 mm (9¾ in) long by 130 mm (5⅛ in) wide and has scales with long recurved bract (umbo) and weigh up to 1 kg. They appear on different trees (dioecious) during early spring and the female cone matures in 20 months.

Fruit: The globular female cone matures in 20 months and is up to 500 mm (20 in) in circumference. It contains numerous light brown seeds that are up to 50 mm (2 in) long by 20 mm (¾ in) wide and have a narrow wing and can weigh up to 7 g. The largest seeds tend to be more viable and produce stronger seedlings.
