There's a new attraction in Lamoureux Park that's sure to interest nature lovers.

The Lamoureux Park Arboretum is now open for visitors looking to discover more about Cornwall's urban forest. Located on the Waterfront Trail between the Cornwall Community Museum and the Rotary Eco Gardens, the Arboretum showcases 44 different types of tree species that make up Cornwall's tree canopy in one convenient place.

In the Arboretum, there are two of each species planted in pairs, and each tree has a tag that identifies its name in English, French, Latin and braille.

The full tour of the Arboretum would take about an hour to complete. To make it easier to follow along, a map of the Arboretum is available by clicking here.

The City of Cornwall plants a wide selection of tree species during the spring and fall. The tree planting variety list contains varieties best suited to grow in urban conditions. Residents can request to have a specific type of tree planted on the municipal right-of-way in front of their home (click here for species list). City staff will make the final choice based on tree form, site space, overhead utilities, and the soil type in that particular area. The City relies on residents to help with the care of young trees.

Here's how you can help:

• Residents are encouraged to deeply water the tree once a week in dry weather.
• Please use caution when using grass trimmers near the tree.
• Please do not prune or trim the tree.

The City appreciates the help of residents in caring for our trees and our environment. Please click here for a PDF detailing how to care for a tree after it is planted.

For 2024, we have selected trees that are tolerant to pollution, drought, and road salt.  The selected species are also currently resistant to invasive insects and disease.  The most common constraint for tree planting is the size of the area available for the tree, both above and below the ground.  Here you'll find a list of trees that the City of Cornwall plants, sorted by height.
