The Australian wildflower industry began in the 1870s based on collections made by Cook and other explorers. It has been revitalized recently by cutting plant material from natural stands in the wild. Records of harvesting indicate that >1000 species have been harvested for commercial purposes but this is now declining due to the development of plantations of selected clones and species, and because diseases are having an increasingly severe impact on natural populations. Increases in market standards are also having an impact. The Australian native cut flower industry is centred now on three species only (Chamelaucium, Anigozanthos and Banksia). Nursery production of plants for general ornamental purposes has been very dynamic in terms of species available for purchase and there is every indication that this trend of high species turnover is continuing. Research programmes are concentrating on these three cut flower species and this paper outlines research on two of these, Chamelaucium and Anigozanthos. In Chamelaucium, research has been concentrated on developing improved agronomic and postharvest practices and more recently on the documentation of the genetic resource of which only a small part has been described to the present time. Research on Anigozanthos has been directed more towards genetic improvement and thirty years of advanced breeding are outlined. Significant developments have been the development of triploid and tetraploid interspecific hybrids and the capacity to transfer pest and disease tolerance from A. flavidus into the hybrid lines.
