June 17, 2011, Vineland, Ont. – New research sponsored by the Canadian Ornamental Horticulture Alliance (COHA) at Vineland Research and Innovation Centre (VRIC) and Nova Scotia Agricultural College will assess plant diversity and survival issues for green roofs.
“Multi-year survivability has been an ongoing issue for green roof habitats in Canada. With this research we are particularly interested in moving away from the more common plantings dominated by sedum species to a broader selection of native plants that demonstrate sun, wind, cold and drought tolerance,” said Dr. Rumen Conev, an ornamental plant breeding researcher at Vineland.
With over 20 new native species being studied, a green solution to making Canadian buildings more energy efficient could be right under our feet.
The environmental benefits of green roofs are already well-documented – significant reductions in building heating and cooling costs, stormwater runoff management, and natural habitat creation. However, a lack of research into planting options and managing green roof health in Canadian climatic conditions has been a barrier to greater usage.
“Canadian cities are lagging behind in North American green roof rankings”, said Andy Kuyvenhoven, president of both Kuyvenhoven Greenhouses Inc. and the COHA. “Growers and nurseries have a suite of native plants that we believe can do the job.”
This research, he added, will confirm the best choices from dozens of species that are already highly adapted to and can help resolve the issues of the Canadian conditions.
“As a grower I am interested in understanding how best to start plants in the nursery to ensure successful transition to a green roof habitat,” said Bill Stensson, president of Sheridan Nurseries Ltd. “Our industry wants to see a green roof explosion in this country with planting materials that can survive for 50 years, not one or two.”
Funding for this research was received in part from Agriculture and Agri-Food Canada’s agri-science cluster initiative. Vineland’s green roof research initiative will be on display beginning in June 2011 at Vineland Research and Innovation Centre in the heart of Niagara’s horticultural zone.

The Canadian Ornamental Horticulture Alliance is the national voice for the ornamental horticulture industry in Canada and is a strategic alliance of three broad based organizations: the Canadian Nursery Landscape Association (CNLA), the Fédération Interdisciplinaire de l’Horticulture Ornementale du Québec (FIHOQ), and Flowers Canada Growers (FCG). These three organizations work together through COHA to coordinate industry action, contribute to effective public policy and speak with one voice on issues of concern to the sector as a whole.
Vineland Research and Innovation Centre is an independent, not-for-profit organization that was created to be a world-class centre for horticultural science and innovation. In its capacity to enable and foster relationships with industry, academia and government, Vineland works to deliver premium product and production innovations. Vineland brings a global perspective to the Canadian horticulture industry and offers a broad range of lasting benefits to stakeholders both locally and internationally. Aligned with industry needs, Vineland’s research priorities and outcomes are focused on the growth of the entire horticulture industry. Vineland is funded in part by Growing Forward, a federal-provincial-territorial initiative.
