Insights from a veteran trial garden manager
By Karina Sinclair

The Landscape Ontario trial gardens showcase the innovative ornamentals coming to market in the near future. Featuring nearly 600 different kinds of annuals, perennials, and woody shrubs, it’s a spectacle for the senses.

Rodger Tschanz, lecturer at the University of Guelph, has been managing and evaluating the performance of new releases in the trial garden since 2006. He joined the Landscape Ontario Podcast to reveal some of his favourite blooms from the 2023 trials, some observations from his wildflower trials in collaboration with the World Wildlife Fund, a glimpse of an interesting plant project involving student wellness at the University of Guelph, and how his attitude toward gardening has evolved to better appreciate plants that look good dead, thanks to the influence of Dutch landscape designer Piet Oudolf.
