Wollemi Pines planted at Kew reach maturity

The first Wollemi Pine planted outdoors outside of Australia by Sir David Attenborough in May 2005 along with the tree planted in April 2006 by its discoverer David Noble at RBG Kew both now bear male and female cones. This makes these trees amongst the first Wollemi Pines in the northern hemisphere to reach sexual maturity.

 

Research carried out at Royal Botanic Gardens, Sydney and Mount Annan Botanic Garden, Mount Annan, in Australia shows that female and male cones are produced on adult trees with pollen release from the male cone occurring in spring. Seed cones mature 16–19 months later in late summer and autumn and appear to be produced annually. Approximately 10% of the seed produced in two consecutive years was viable. Germination of this seed took up to 6 months – so it could be another 2 years before we see any seedlings appear.

 

wollemi survival in a cold European winter

Posted on behalf of Dara Wyer by Mark Taylor

Just to let you know that I have a wollemi in county Dublin. It is in a large pot and has survived very well through a sustained cold snap lasting over three weeks with temperatures going as low as -12 C. One thing I did notice was that it seemed to shed some branches- two of them came off as soon as I brushed past them. This may be a survival thing or the plant may be stressed- hope this is of interest.
