Dominion Arboretum

Dominion Arboretum is a tree garden located within the Central Experimental Farm that spans about 64 acres with rolling terrain between Prince of Wales Drive and the Rideau Canal. The grounds contain roughly 4000 specimens representing diverse trees and shrubs suited to the region's climate.

The arboretum was founded in 1889 to test how woody plants could survive harsh Canadian winters and climate conditions. Scientists methodically observed and recorded which species adapted well to the region's weather.

The site serves visitors as a place to learn about plants and spend time outdoors reconnecting with trees. People walk the paths to discover different species and experience how diverse woody plants grow together.

The grounds are open from sunrise to sunset with no admission fees required for entry. Parking areas, restrooms, and accessible paths make it straightforward to explore the site on foot.

A Bebb's Oak over a century old thrives here, showing how long individual trees can live under Canadian conditions. The site sits north of the 45th parallel, where harsh winters limit which woody species can flourish.
