The Wollemi Pine is bisexual (monoecious) and produces small male and female cones on the same tree.
The cones appear on the tips of separate branches from about 9 years of age.
The seeds are produced by the round female cones and the long male cones produce the pollen.
During the colder months, the Wollemi Pine becomes dormant and its growing buds develop an attractive white waxy coating with ruby pink lines. This protects its growing tips and is thought to have helped it survive many ice ages. When spring arrives, the caps disappear and the new growth bursts through. It is not uncommon for new buds (from one to multiple) to grow from beneath or through the polar cap.
