The Alberta Perennial Trials is a research and demonstration project that evaluates new herbaceous perennials for the Alberta region. New perennial species and cultivars are monitored at three test sites for a period of three years. Results are published in the form of a technical industry report and public documents.

The first research and demonstration of herbaceous perennials was held at the Calgary Zoo and Botanical Gardens in 1999 – 2001. The Alberta Perennial Trials were established in 2002 and includes test sites at Olds College Botanic Gardens, the Muttart Conservatory and the Calgary Zoo and Botanical Gardens. This expansion to three test locations allows for evaluation of plant material under a broad range of Alberta’s diverse growing conditions. All three sites are open to the public to come and visit. It`s a great way to see what is doing well in Alberta`s challenging growing conditions.
