Black Walnut vs Yamhill Hazelnut
Juglans nigra
Corylus avellana Yamhill
NOT AVAILABLE THIS SEASON
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.
The Yamhill Hazelnut is a tasty, relatively cold hardy hazelnut that is a popular European variety.
It is known to be a strong grower and has moderate eastern filbert blight resistance. It is a suitable pollinizer for the York Hazelnut and European Hazelnut.
Introduced by Oregon State University, The Yamhill Hazelnut is used by Ferror Roche for their candy and chocolate spread desserts.
Not all hazelnuts pollinate with each other so it is important to pick the correct pollination pairs. Two compatible varieties of hazelnut are required to produce nuts. Nuts will only be produced once maturity is reached, around 2-3 years.
