Black Walnut

The eastern black walnut is native to a wide region of eastern North America that extends northward into Southern Ontario and Quebec. Strains adapted to prairie conditions have been moved northward into Manitoba and beyond. It is well adapted to eastern North American climatic conditions. The black walnut is prized for its timber as well as the rich flavoured kernels. Our selections were collected from the best trees across the native range for cracking and filling quality as well as hardiness. Seedlings are grown from our best trees. The Duke nut cracker is the best tool for cracking these nuts. Tree size can be 20-25 m (80 ft) in height and spread 20 m (50 ft) at 100 years.
