She continues to contribute to various industry publications; willingly shares her knowledge and believes we are privileged to work with the world’s most beautiful floral products.

Bettina Gollnow

The easy, readable style and appealing design reflects the expertise and attention to detail of the technical editor Matthew Stevens to whom the authors are most grateful.

Bettina Gollnow is currently the Communications & Extension Manager for WildFlowers Australia, the national industry association focusing on the marketing and sales of cut flower and foliage products of Australian and closely related South African species for the floristry industry. Prior to that she provided extension support to the commercial NSW cut flower industry as the Industry Development Officer (Floriculture) for the NSW Department of Primary Industries for over 18 years.

During that time, Bettina brought industry members together through publications, industry events and technical resources. She also completed two projects for RIRDC, firstly developing the 2005–2011 Wildflower and Native Plants Industry R&D plan and reviewing the achievements of the previous plan. Subsequently she led the project to develop the quality specifications for Australian wildflowers and the supporting post-harvest manual.
