Rottnest Island Pines (Callitris preissii) are fairly common in the more coastal areas of Perth – and on Rottnest Island of course. In fact, these are about the only places where you will find this tree growing wild.
It’s reported flowering season is Jan-Dec, but you would hardly notice the flowers, which look fairly small and insignificant. We saw this one in flower on a limestone outcrop in North Fremantle recently. The flowers eventually turn into distinctive cones.
