• A great tree for larger landscapes and natural areas. Placement should be considered as the litter from the nuts can be messy. Juglans produce the chemical juglone, and many plants are highly sensitive to this chemical. Look for plants with a tolerance to the toxicity near or under juglans. A great tree for attracting squirrels.

• Native to Ontario and other parts of North America.Native Americans used the nuts for food and boiled the tree sap for syrup. They also reportedly threw the husks into ponds to poison fish, making them easier to catch.Larval host for a bunch of butterflies and moths, including at least two specialist moths, the Regal Moth and Luna Moth. The flowers are wind-pollinated, with male and female flowers on every tree, but opening at different times, to encourage cross-pollination with other trees. The nuts are favourites of many species of birds and some large and small mammals.
