To assist with research into, and cultivation of, selected Australian plants including the Wollemi Pine (Wollemia nobilis), Waratah (Telopea speciossima) and Flannel flower (Actinotus helianthi).

Research interests

  • Growth of Wollemi Pine in response to environmental stresses such as drought and disease
  • Initiating tissue cultures of new species of interest, such as Persoonia and Amborella spp.

Current work and research projects

  • Propagation of the clonal collection of Wollemi Pine for the establishment of ex situ populations at the Australian Botanic Garden Mount Annan and the Blue Mountains Botanic Garden Mount Tomah
  •  Providing assistance in growth trials of the Wollemi Pine in response to water stress and varying light levels
  • Maintaining stock tissue culture collections of several varieties of Flannel Flower
  • Maintaining potted collections of selected Waratah hybrids for use in future research and breeding programs
  • Overseeing the initiation of cultures of epiphytic orchids by volunteers (for eventual sale through the ‘Growing Friends’).
