Patterson Garden Arboretum

The University's Arboretum was established in 1966 and contains one of the most diverse collections of trees, shrubs, and vines in the Prairie Provinces. Many specimens from the 1960's are still thriving, fruiting, and flowering while they support lichens, birds and bees. New trees and shrubs are settling in to shady and sunny spots between the old canopy. Species from northern regions of the world as well as historic cultivars developed by pioneer plant breeders are on display. All specimens are labeled with common and scientific names. An invaluable reference for horticulture and botany, the picturesque site is also used for photography, field trips, and strolls.

The Arboretum is located in zone 2b of the hardiness zones of Canada, experiencing a sunny continental climate with cold snowy winters and hot summers.  Despite climatic extremes, many woody plants thrive here, responding to well-defined seasons and long hours of summer sunshine.

Patterson Garden Arboretum is a garden attraction of Canada's Garden Route.  It is nearby to the campus area and is open to the public throughout the year, free of charge, from sunrise to sunset.
