Originally begun in 1889, the Arboretum covers about 26 hectares (64 acres) of rolling land between Prince of Wales Drive, Dow's Lake and the Rideau Canal.
Carleton University is located at the opposite side of the Canal.
It displays a wide range of well-established trees and shrubs with the intention of evaluating their hardiness, including 1,700 different species and varieties.
This has allowed for a collection of magnolias, azaleas, and several other fringe trees including Metasequoia and Liriodendron.
In this area are located the annual plant display, perennial borders, lilac walks, roses and hedges.
