Propagation
Stratify fresh seeds for 2 months during winter and sow in pots, then place in a cold frame to germinate

Note:
Care should be taken when selecting a sight as the tree has vigorous roots that can lift concrete and block drains.

Botanic information
Leaf: The persistent linear leaves are arranged in bundles of 5 and persist for 2-years. The soft textured leaves are dark green and paler underneath with white stomatic bands that give them a bluish-grey colour. The sheath is up to 12mm (½in) long and when young the bundles may have tufts of hairs at the base.
Note
The ovoid olive-brown buds are up to 6mm (¼in) long and are resinous. The scales extend to the pointed apex.

Flower: The small pinkish-green female flowers form cones and the yellowish-green male catkin-like flowers are arranged in a dense cluster that appears during spring.

Fruit: The cylindrical pendant cones are green ripening to brown in the second year and are arranged in clusters towards the end of the branches. The smooth unarmed scales open wide to release red-brown winged seed that are up to 25mm (1in) long.
