Good Morning,
Could you help to figure out what kind of the tree (as attached) is?
I try to buy a similar one for my backyard.
Thanks
Ren
Your photograph shows what appears to be a Black Walnut tree, Juglans nigra. Most of the major large nurseries in the Toronto area should be able to supply this tree, but you should probably phone first to be sure. If you are unfamiliar with your local large nurseries, you could take a look at the Landscape Ontario website, which has a comprehensive listing of nurseries in the GTA: https://landscapeontario.com/garden-centres/chapter/toronto
You should also be aware that Juglans nigra produces a chemical called “juglone” which some plants do not tolerate well when planted nearby. The Toronto Master Gardeners’ Guide to Juglone and Black Walnut may be helpful here in determining what to plant near this tree: https://www.torontomastergardeners.ca/wp-content/uploads/2016/03/Juglone-and-Black-Walnut-A-Toronto-Master-Gardeners-Guide.pdf
