The inaugural International Trials Conference will take place on 4-7 July 2011 at RHS Garden Wisley, and will act as a global consultation on the assessment of ornamental plants.
Organised in collaboration with the International Society for Horticulture Science, the event will bring together growers, breeders, nurserymen and commercial suppliers to discuss regional, climatic and cultural variations on trials carried out at both national and regional levels.
RHS director of horticulture Jim Gardiner said: "We are very excited by the opportunities that the conference will bring.
"We have been managing plant trials since the RHS was founded over 200 years ago and our trials programme along with the Award of Garden Merit (AGM) is very much an integral part of our charitable mission."
RHS head of horticultural trials and relations Kylie Balmain commented: "Our trials programme is world renowned and we have visitors from a wide variety of countries coming to see what we are doing – this conference is a great opportunity for us to learn and share."
