Australia is the driest and hottest inhabited continent in the world. Our unique flora and fauna have evolved over millions of years in changing climatic conditions. More recently our Indigenous flora and fauna have been impacted by foreign settlers who have significantly altered the natural landscape for farming, mining, forestry and the establishment of our settlements and cities.

Professor Chris Daniels is a renowned, internationally acclaimed, Urban Ecologist and author. For over 20 years, he has entertained and informed audiences with his knowledge, wit and skill – commentating on Australia’s unique fauna and flora and their interaction with man-made environments or man-made decisions. In August 2021, an independent jury convened by The Advertiser (South Australia’s major daily newspaper) voted Chris second in the State’s 50 most influential Environmentalists.

This keynote address will introduce the audience to Australia’s unique habitat and the animals and plants that call Australia home and also explore the changing human impacts on the natural environment.

Step back in time as John enlightens us about Australia’s pioneer rose breeders starting with Alister Clark, Australia’s most prodigious pioneer rose breeder who released 122 roses during his lifetime. Next came Olive Fitzhardinge who blended society life with breeding hybrid tea roses during the 1930s. Frank Riethmuller is remembered for his highly prized cultivars released during the 1950s. The common thread being roses which were hardy and well suited to our climate.

Jacques Mouchotte – LINEA ROSA®: A database of Rose Lineage

Renowned Rose Breeder and author, Jacques Mouchotte was born in France and had a long and distinguished career working for the House of Meilland from 1978 to 2013. From 1993 until his retirement, he was the Director of Research for all breeding programs and introduced several hundred new rose varieties with many winning multiple awards. He attributes his rose breeding success to his mentor Mme. Marie-Louise “Louisette” Meilland (1920-1987).

Some of Jacques well-known varieties are Bonica, Debut, Carefree Wonder and Pierre de Ronsard as well as the Romantica Series, modern roses with an old-fashioned look, such as Yves Piaget. In the 1980s and 90s he developed Meillandina® miniature roses and Meidiland® landscape roses and from 2006 experimented with the concept of Drift® roses, ideal for small gardens. His many achievements include 2 Hall of Fame roses, 11 All America Rose Selection, 26 ADR champions and 91 Gold Medal winners in rose trials worldwide.

LINEA ROSA® is a comprehensive database of rose lineage created between 2013 to 2021, involving a massive 2,500 working hours compiling 20,668 entries. This fascinating presentation reveals the sources, research and dedicated work to create this important database which is maintained by the American Rose Society. It is a great research tool which provides rose descriptions with instant genealogy, genetical background and search options. A project of this magnitude is rare indeed.


An award-winning South Australian winemaker and farmer, Rose Kentish describes herself as a flavourist; she has been making wines since 1998, spirits since 2010 and dabbles in perfumery after completing Level 2 studies in Grasse, France. Her wines have received enthusiastic praise from Australia’s top critics, such as ‘these are cult wines’ (Decanter) and ‘Cult wine in the waiting’ (Max Allen) and have won numerous awards, including Rose named inaugural AWIW Australian Winemaker of the Year 2015.

In 2016, Rose co-founded Sparkke, a for-purpose brewing company. Then, in 2020 she brought to life a series of spirits, made from aging brewed products and local botanicals, including roses.

In mid-2020, Rose and her husband purchased a farm on Kangaroo Island and are working to bring the bushfire-ravaged land back to productivity. There, they hope to plant botanicals for use in future distilling and perfume.

Rose’s passion for scent and flavour has been the drive behind her intrigue of using roses in beverages. Their fragrance, and the flavour from delicate essential oils that she has managed to extract from their petals, has enhanced a range of beverages now sold commercially.

This thought-provoking lecture will explore the distilling method to extract pure essential oils from roses, a subject which has fascinated Rose Kentish for many years.  She used her perfumery studies to really accelerate and concentrate her interest and practical extraction of rose oils on both a 5L trial still and 200L production still. Through many trials, she tested different varieties of roses and the ultimate perfume and flavour extraction. Colour of the rose, variety, rose lifecycle and placement of the rose in the still have all affected the results.

Rose has made gin, vodka and vermouth using rose petal oils. The results are fascinating, but only the start of many more trials. And while the trials continue, the commercially available beverages are proof of the delicate, subtle and delicious qualities of roses in beverages.

ALLAN CAMPBELL OAM    –    SIR HANS and NORA HEYSEN: The history of Roses in their garden at ‘The Cedars’ and in their paintings

Allan Campbell is the Curator at The Cedars, Hans Heysen’s magnificent estate in Hahndorf which is now under the custodianship of the Hans Heysen Foundation. Allan completed extensive studies in teaching (at Wollongong Teachers College, University of Wollongong, and University of New South Wales), horticulture and landscape design (at Ryde School of Horticulture), and art (at the National Art School). He moved to Adelaide in 1980 and established a specialist retail plant nursery and landscape design consultancy in the Adelaide Hills. Since 1994 he has married his passions in education, gardens and art overseeing and promoting the Hans and Nora Heysen Foundations’ Collections. Allan has been awarded an OAM and Centenary medals for services to Conservation, Environment and Art.

Hans Heysen (1877 – 1968) remains one of Australia’s most popular and best loved artists. Although he is remembered more for his iconic landscapes of the Adelaide Hills and Flinders Ranges of South Australia, he was also a master flower painter. His superb oil paintings of roses picked from his own garden provide a wonderful record of the history of this unique artist’s garden. The garden continued to evolve through two further generations of Heysen family ownership. Over 300 roses continue to grow and flourish at The Cedars from the earliest plantings of Bourbons, early Teas and Musks in the 1920s and ’30s through to a wide variety of Hybrid Teas and Floribundas as favoured rose varieties of subsequent family members. Hans’ daughter Nora Heysen (1911-2003) established her own reputation as one of the nation’s finest exponents of the art of still life painting.
