• 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. Butternut is similar in appearance to black walnut (Juglans nigra), however, it is generally smaller, its bark is smoother, it has fewer leaflets per leaf, and its nuts are more oval than round. Native Americans used the nuts for food and boiled the tree sap for syrup.Larval host for a bunch of butterflies and moths, including a specialist moth, the Walnut Sphinx. 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. However, due to a pathogen, butternut canker, there are fewer trees, concentrating the needs of the dependent species on fewer trees. The sweet high-fat nuts are favourites of many species of birds and some large and small mammals.
