HEARTNUT (Varietal form of the Japanese Walnut) 
(Juglans sieboldiana, var. cordiformis ) 
The heartnut is not nearly as well known as it should be. It is a very 
fine nut and one of the best ornamentals of any of the nut species. 
It bears annual and good crops of easily cracked nuts the kernels of 
which, in the varieties we list, come out in whole halves, nearly 100%. 
It does not ordinarily present a pollinizing problem as it is very readily 
pollinized by the wild butternut, you will often wonder where the pollen 
could have come from. 
The heartnut does present somewhat of an insect and disease prob- 
lem. For further discussion of this, we refer you to our booklet, “Prac- 
tical Nut Growing.” If you live in a locality where the brooming disease 
of walnut is prevalent, it is not advisable to plant heartnut trees. 
The heartnut tree is one of the most rapid growers of any of the nut 
species. It also bears at a very early age, often the third year after 
transplanting of the grafted tree.

logue.
