The story
The white walnut was gathered by Haudenosaunee and Algonquian peoples for its rich, oily nuts and tapped for syrup like maple; the hulls dyed cloth butternut brown, the colour of Confederate homespun. Butternut canker has killed most wild trees since the 1960s.
Planting
Full sun, deep moist soil, and distance from susceptible plants, since it makes juglone like black walnut. Plant canker-resistant stock or a hybrid buartnut.
Growing
Water young trees; mulch wide. Prune in late summer only. It is shorter-lived than black walnut.
Harvest and use
Nuts fall in early autumn in sticky green husks; hull, wash, cure two weeks, and crack. The oily kernel is the sweetest of the walnuts.
What to watch for
Butternut canker above all; squirrels.
