Trillium Park Plant Identifier Project

Trillium Park Plant Identifier Project

The inception of Trillium Park focused on creating an identity whose core stemmed from diverse ecological zones and the inclusion of First Nations symbols, stories and language. As part of ongoing efforts to enhance park offerings, Ontario Place worked with key collaborators Walter Kehm, former Principal, LANDinc; Professor Jonathan Ferrier, PhD, BSc, BA, Michi Saagiig Anishnaabe; and William (Bill) Deluca, Founder, Aldershot Landscape Contractors to develop the Trillium Park Plant Identifier Project.

The goal of the Trillium Park Plant Identifier Project is to provide information about Trillium Park’s botanical diversity. Visitors are encouraged to learn how to identify various botany with the installation of plaques throughout the site that call out the English, Ojibway, French and Latin names of each plant. The use of the Ojibway language is an integral representation of Ontario’s Indigenous heritage of living and working in harmony with nature. In addition to the plaques, visitors are welcome to explore Trillium Park digitally with a pop up map full of fun facts around how each plant was once used for either consumption and/or medicinal purposes in the past.

We acknowledge the land on which we are walking is the traditional territory of many nations including the Mississaugas of the Credit, the Anishnabeg, the Chippewa, the Haudenosaunee and the Wendat peoples and is now home to many diverse First Nations, Inuit and Métis. We acknowledge that Toronto is covered by Treaty 13 with the Mississaugas of the Credit. We are grateful to walk this land and we give thanks to the first peoples of Tkaronto, for being keepers of the sky, earth, and water.

    Walter is a passionate lover of nature who began his career in forestry and then landscape architecture at Syracuse University. He honed his skills in landscape architecture and urban design at Harvard University followed by post-graduate studies in Italy. Walter has designed significant open spaces, parks and recreation facilities both internationally and across Canada, including Trillium Park at Ontario Place.

    A key fixture in Walter’s career has been his work with First Nations communities throughout Canada in support of efforts to create sustainable community development plans. Walter worked in close collaboration with the Mississaugas of the Credit to incorporate significant indigenous symbols and flora into the design of Trillium Park.

    A note from Walter:
    Since Trillium Park opened, visitors have expressed an interest in learning more about its plant life. In response to this growing interest from the public, plant identification plaques that incorporate four translations were installed throughout the park to promote public education and engagement. The intent is to have school children and other park visitors study the plants and learn about their ecology, food, and medicinal uses. The use of the Ojibway language is important to remind people of Ontario’s Indigenous heritage with its rich history of living and working in harmony with nature.

    A note from Bill:
    It was my sincere pleasure to work with Walter Kehm on the creation of Trillium Park. It has become, in the history of my firm, one of its most prestigious projects. When Walter approached me to become involved in the teaching aspect of this site, I immediately agreed to support his vision of identifying the various flora found throughout the site. We were more than eager to donate labour and materials in support of the project. I sincerely hope everyone will have a great experience when visiting Trillium Park and will learn from the educational plaques placed throughout it.
