Black Walnut

The Frank Hazelnut produces nuts that are medium size and ripen mid August. This is one of the best eating hazelnuts for cold climates. It is a medium size deciduous tree from Saskatchewan, Canada. It is a productive tree that has been tested as both a pollinizer and a main crop cultivar for colder climates. The Frank Hazelnut is one of the cold hardiest hazelnut trees on the market and known to be resistant to eastern filbert blight.

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.

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.
