Cook Pine


Araucaria columnaris
Family: Araucariaceae
Common Name: New Caledonia Pine, Cook Pine, Cook's Araucaria

General Facts:
• Evergreen coniferous trees
• Mostly dioecious, with male and female cones found on separate trees, though occasional individuals are monoecious or change sex with time
• Female cones are usually found high on the top of the tree; vary in size between species from 7-25 cm diameter. They contain 80-200 large, edible seeds. Seeds nutlike, triangular, with membranous wings.
• Trunk has tendency to curve or lean, giving tree a dramatic silhouette.
• Leaves dark green, small and needle-like (0.5-1.0cm long), closely-overlapping and spiralling densely around twigs, giving branchlet an appearance of a plaited cord. Tree sheds whole branchlets rather than individual leaves.

Interesting Facts:
• Named after Captain James Cook, who discovered plant on Isle of Pines in New Caledonia.
• Seldom grown along roadsides, as soot and dust tend to cover fine leaves.

Uses:
• Young potted trees can be used as Christmas tree substitute in tropical regions.
• Commonly planted as timber tree elsewhere for its lightweight softwood, decorative and straw-coloured, used to make furniture and bowls.

Food Facts:
• Seeds are edible but cones and seeds seldom produced in Singapore.
