General Info
Cultivation: Fast-growing, drought-resistant. Somewhat salt-tolerant . Relatively free of pests and diseases in Singapore. The fine-textured leaves tend to be covered by soot, so this tree tends not to grow well in industrial areas or along highly polluted roads.
Botanical Features
Form: Tall evergreen conifer, grow up to 50-70 cm tall in natural habitat, 25-30 m in Singapore.
Leaf: Small (0.5-1.0 cm long), needle-like, slightly curved, arranged in dense spirals around twigs. Whole leafy twigs (rather than individual leaves) are shed during leaf drop.
Flower: None-flowering plant. Cones produced at branch tips. Male and Female cones are found on separate trees. Male (or pollen) cones long, cylindrical, female (or seed) cones larger and broader (10-15 cm long, 7-11 cm wide).Cones are seldom produced under local conditions _hot and humid equatorial climate.
Fruit: Large, broad, woody cones, formed from fertilized female cones, holding nut-like seeds.
Trunk: Relatively straight or slightly _ leaning in native habitat, but may curve quite dramatically in Singapore.
Points of Interest
Although commonly called a “pine” tree, Cook’s Pine is actually not a true “pine”(genus: Pinus), but may be regarded as a distant cousin. Wood is decorative with interesting knots, and is used to make furniture and bowls.
Related Species
The juvenile plants of the similar – looking Norfolk Island Pine (Araucaria beteropbylla) are often mistaken for those of Cook’s Pine.
