Propagation
The seeds have no dormancy period and are sown when collected in pots. In cool climates place the pots in a cold frame to germinate. 

Note:
Generally Pinus species tolerate pruning of the new growth during spring to early summer to force lateral buds to form and some cultivars may be trimmed to form a hedge.

Botanic information
Leaf: The forward pointing stiff linear leaves are arranged in fascicles of 2 and have a pointed apex. The stomatic bands appear on all surfaces and the basil sheath is up to 12mm (½in) long. The leaves persist on the glabrous branchlets for up to 6-years.

Flower: The male catkin-like flowers appearing in pairs or in a small cluster at the end of the branches and the sessile female cones are purplish when young. Both appear on the same tree (monoecious) from late spring to early summer.

Fruit: The ovoid yellow-brown cones are solitary or in clusters of 3 and the scales have a short acute umbo at the thickened apex.
