The Frédéric Back Tree Pavilion, set in the northeast corner of the Jardin botanique de Montréal, opened its doors in July 1996.

The goal of the Tree Pavilion is to highlight the importance of trees and forests in our lives and showcase the Arboretum's collections.

The Frédéric Back Tree Pavilion is located on Rosemont Boulevard, between 28th and 29th Avenue, east of Pie-IX Boulevard.

Address for paratransit: 4500, boul. Rosemont. Please do not use as postal address.

The Rosemont Boulevard gate is open until 6 p.m.



The Frédéric Back Tree Pavilion introduces visitors to the scientific, ecological, economic, artistic and cultural dimensions of trees, in both cities and forests.

Through its outreach activities it makes people aware of the roles played by trees in different aspects of our lives, and in the ecological balance of many ecosystems.



During the summer, discover the best-kept secret of the Tree Pavilion: the extensive collection of miniaturized trees on display in the Courtyard of North American bonsai.

Also don't miss the various activities offered to the general public, as well as to students.

To round out your visit, take a tour of path around the tree pavilion pond and explore the impressive collections of trees in the Arboretum.



The architectural design is based on an interpretation of the tree shape symbolizing a pillar.

In keeping with the theme of the site, wood in different forms and worked in different ways was used as the basic material.

Local wood, from species found in Quebec and elsewhere in Canada, has pride of place.

White pine, balsam fir, white spruce, sugar maple, yellow birch and Douglas fir were all used in the structure or finish. The supporting beams, large pieces of laminated white spruce, were made especially for the Tree Pavilion.

The arrangement of space and volumes is inspired by three major shapes from the classic garden repertory, i.e. the alley, path and grotto.

The alley

The laminated wood columns supporting the roof of the Tree Pavilion represent the royal alley, lined with straight rows of trees. The alley continues outdoors, onto an observation deck.

The path

The permanent exhibition room is bathed in natural light and looks out onto the Arboretum, its sinuous shape evoking a romantic path on the edge of the forest.

The grotto

The temporary exhibition room, more shadowy and without any windows, is like a mysterious cavern full of treasures waiting to be discovered.


The description of the architecture of the Frédéric Back Tree Pavilion was inspired by an article by Simon Péloquin, published in Quatre-Temps magazine (Vol. 21, No. 2, summer 1997).



Discover the Jardin botanique de Montréal's fabulous tree collections!

Over half the total area of the Jardin botanique de Montréal is devoted to the Arboretum and its impressive collections. Its 40 hectares are home to almost every species of tree capable of growing in our climate.

The Arboretum has about 7,000 specimens of trees and shrubs, in 50 collections. There are species native to Quebec and many cultivars imported from all over the world. All are identified and grouped by family and genus.

In this veritable forest in the heart of the city, visitors can see the way nature changes from season to season. The buds and flowers burst open in spring and summer. Fall is a perfect time for a stroll to admire the colourful leaves and fruit, while winter is nature lovers' favourite season for birdwatching and cross-country skiing in the peace and quiet.

Blooming times for the main tree groups

May: crabapples (Malus) and cherry trees (Prunus)
May to June: rhododendrons (Rhododendron) and lilacs (Syringa)
Early June: chestnuts (Aesculus)
Mid-June: locust trees (Robinia)
June to July: weigelas (Weigela)
Early July: catalpas (Catalpa)

Map of the Arboretum

It's easier to find your way around the Arboretum’s collections if you use the map. The trees are grouped by botanical category.


Ash Woodland

The Ash Woodland is one of the few naturally regenerated wooded areas at the Jardin botanique. The path through the woodland is popular with walkers and nature lovers. The canopy here is dominated by close to 500 red ash trees (Fraxinus pennsylvanica) and more than 200 American elms (Ulmus americana). Until recently, however, there were a number of invasive species in the undergrowth and very few native species.

The Ash Woodland restoration project was launched in May 2008 with funding received by the Friends of the Montréal Botanical Garden through the Environment Canada EcoAction Program and the support of different partners. The work began with the removal of thousands of buckthorn (Rhamnus cathartica) and cow parsley (Anthriscus sylvestris) plants, both invasive species. Then a wide variety of suitable native plants including trees, shrubs, ferns and grasses were added.


The Pond

Major redevelopment work was carried out on the Frédéric Back Tree Pavilion pond in 2002, and it continues to evolve and add to its beauties year after year.

The paths, interpretation panels and visitor activities will help you better understand and appreciate this native habitat, covering more than 3,000 m2.

Four interpretation stations have been set up on a path that runs in a 400 m loop. As you stroll along it, you can find information on wetland ecology, and on the most popular animal and plant species inhabiting the pond. For example, you’ll learn how to tell dragonflies from damselflies and diving beetles from water beetles.

The pond is also an excellent spot to see ducks and other birds, as well as many different small animals and insects. It is teeming with life!
