Description

A native conifer growing as a small tree or shrub up to nine metres high that grows in an upright, dense, conical form and has fissured bark. It has soft green foliage and globular woody fruits, often exuding a sticky sap. Produced in late spring the flowers are yellow-orange, and they are often associated with the phenomenon of pollen clouds being emitted during the warmer spring months.

Callitris preissii is restricted to calcareous dunes in the Perth region and on Rottnest Island. It appears to also be native to the escarpment in Kings Park and adjacent to Bold Park in the coastal dunes of the Campbell Barracks.

This species, being a classic lover of coastal regions, is ideal for windbreaks or enhancing large open spaces. Planting in large groves produces an enchanting forest effect within a parkland environment.

Horticultural tips

  • This species is not suited to long-term pot culture.
  • Quick growing tree, which prefers to be planted in full sun, with watering to establishment.
  • These trees grow in varying topographical situations, making them suitable for reclaiming sandy slopes.
  • Can be prone to insect borers.
  • The Rottnest Island Pine is fire sensitive; however the timber is sought after for a variety of uses, and is thought to be termite resistant.
