Callitris rhomboidea, Port Jackson Pine, Oyster Bay Pine



Callitris rhomboidea is known as the Port Jackson Pine or Oyster Bay Pine. The common name depends on the location of the species. The former name refers to populations in NSW whist the latter common name refers to those in Tasmania. We will stick to Port Jackson Pine because of our location.

The Port Jackson Pine is a small tree that may reach a height of 15 metres. Mature trees have an attractive pyramid shape.

The foliage may be dark green or have a bluish tinge.

Male and female cones are carried on the same plant. Mature female cones are clustered on fruiting branches and remain, on the branch, for many years. The female cones illustrated are at least five years old. They form as attractive feature.

C. rhomboidea is said to be the most ornamental of the native cypresses. Use as a “stand alone” specimen or in a hedge or screen are some of the domestic uses of this most attractive tree. The dense foliage will provide safe nesting sites for small native birds.

C. rhomboidea, once established, in common with other native species, are tolerant of drought. This makes them ideal substitutes for exotic cypresses that come from areas with high rainfall. This makes them more susceptible to our prolonged droughts.

The timber has proved to be termite resistant but is not plentiful enough to be of any particular economic importance

The Port Jackson Pine is found in Queensland, NSW, Victoria, Tasmania and South Australia. The species is widespread but not common. C. rhomboidea is naturalized near Auckland, New Zealand.

The species name refers to the rhomboidal shape of the cone scales.

Propagate from seed.
