Black Walnut vs American Hazelnut/Filbert
Juglans nigra
Corylus americana
The Black Walnut is a slow growing, large, straight-stemmed tree with an open crown. It produces dense, very hard, edible nuts.
Black Walnut has a deeply-furrowed, black bark. Its leaves are about 1 foot long, composed of 15 - 23 slightly stalked leaflets on a moderately stout stock which provide good dappled shade.
Despite being highly valued for its edible nuts and its shade tree aesthetics, it is rare to see this tree on the prairies.
Note: Black Walnut's roots produce a substance named juglone that is toxic to some other plants. Consider this when choosing where you plant a black walnut, as you will not be able to grow tomato, potato, cabbage, eggplant, blueberry, azalea, rhododendron, lilac, red pine and apple in the surrounding area.
Note: Plant this tree once. It will not respond well to transplanting.
Note: Although self-pollinating, planting two trees significantly improves nut production.
A top CO2 absorbing species. Experts think this tree may help climate change more than others.
American Hazelnut is a cold hardy, disease resistant, and long-lived nut tree. It is a great choice for a shrub border for wide, open spaces where it will be allowed to spread. Typically used in naturalization projects for its spreading nature, American Hazelnut is ideal for our zone 4 customers.
If you're a zone 3 prairie customer, don't worry! American Hazelnut can still thrive but needs additional care and protection from our harsh prairie climate.
The edible nuts mature from September to October and are usually roasted or eaten fresh. Make sure you take time to notice American Hazelnut's variable and beautiful fall color that ranges from orange, rose, purplish-red, yellow, and green.
Note: You want more than one hazelnut to improve yields.
