This walnut was grafted on black walnut (~J. nigra~) root in 1944 and planted here on low loam soil in 1945. It never has been hardy under our conditions, winter killing some every winter since it was planted. This past winter it was killed to below snow line 18 inches above union, whereas Broadview trees alongside, which are the same in every respect, never were injured until this past winter. Then only minor damage to soft new growth was done. So it looks as though Broadview is still the best bet for our conditions.
I am of the opinion that extreme temperature is not the sole determining factor in causing winter injury to nut or other trees. This opinion is based on the behavior of trees that have winter killed continuously while in certain soil, but on being moved to another spot having enriched soil of similar make-up and drainage located only 200 yards away, have never winter killed since removal, and have taken much worse winters, including the one just past.
The fact that many of our introductions grow and thrive 150 to 200 miles north of here, where temperatures drop to minus 35° to 40°, with occasional drops to 54° below zero. Check this on your map of Interior of B. C. on 53° latitude at Quesnel, B. C. I see a geology map lists that district as sedimentary and volcanic rocks. My informant grows butternuts, chestnuts, and filberts. Another grower at Clinton, located on 50° latitude, central B. C. with temperatures to minus 40° F., grows Japanese and black walnuts, also Pioneer almond. We are sure that the same temperatures with our conditions would kill most of our trees.

Walnut Honey Sandwich
1 Teaspoon crystallized Honey (the coarser the crystal the better) 3 Broadview walnut half kernels or quarters.
Place honey on one-half kernel, then stick the other half on the honey, making a small sandwich, or kernel covered ball of honey. This is a delightful confection.
