Media Release: Internationally renowned rosarian Kelvin Trimper passes away


Kelvin Trimper AM, prominent businessman and urban development manager, internationally respected rose expert, garden and horticulture writer and media personality has died suddenly at the age of 69. Mr Trimper passed away at his Greenwith, SA, home on Sunday, 7 January.

From an early career in education, Kelvin became deeply involved in the integration of education and multi-school campuses into the fabric of the Golden Grove and Mawson Lakes developments for Delfin Lend Lease, leading him to become Community Development Director of those communities, together with other similar entities in Victoria, Queensland and Western Australia.

Since 2012, Kelvin’s consulting business has provided advice to state and local government, not-for-profits and business on property development, collaborative arrangements and agreements between the public, private sectors and community on social, education, environmental and economic development planning. His expertise in this area has seen him present as keynote and guest speaker at OECD Education conferences in Finland, France, Spain, Singapore and New Zealand, and providing advice to government and non-government agencies throughout Australia, the United Kingdom, Singapore and Spain.

Having grown up in Renmark in the midst of his family rose garden with the garden of world-famous rosarian and family friend, the late David Ruston OAM, nearby roses became a passion for Kelvin at an early age. This later saw him develop, along with this wife Melanie, a prize-winning garden of approximately 2000 roses at Greenwith.

Kelvin was active at a state, national and international level as a judge, consultant and rose garden adviser, and was widely recognised for his expertise and community work.

He was the recipient of the Member of the Order of Australia award (AM), the Gold Medal of the World Federation of Rose Societies, the Australian Rose Award (ARA) and the T.A. Stewart Memorial Award (SMA) and was a Fellow of the Urban Development Institute of Australia (SA div), and of the University of South Australia.

Gavin Woods, President of the Rose Society of South Australia and Vice-President of the World Federation of Rose Societies today said “Kelvin was a giant amongst Rosarians. No single individual can possibly fill Kelvin’s shoes. He has possibly contributed more to the rose growing world than any other individual now or in the past.”

A selection of Kelvin’s current and recent involvements include:

  • Chairman, National Rose Trial Garden of Australia;
  • Chairman, World Federation of Rose Societies Convention Committee;
  • Chairman, World Rose Convention (Adelaide) 2022
  • President, World Federation of Rose Societies – 2015 -2018
  • Chairman, Northern Futures Inc.
  • Chairman, Northern Adelaide Industry Leaders Group
  • Deputy Chair, SA Power Networks Community Advisory Committee

Kelvin is survived by his wife Melanie, daughter Kirsty, son Adam and daughter-in-law Ruby.
