Still on trial, Grimo 89 is a cross between Campbell CW3 and Imshu. It produces medium to large sized nuts that crack perfectly when cracked on the edges. It allows the nut meat to drop out whole and has 29% kernel. Cold hardy to USDA zone 6.
Partially self-fertile - can produce much more if planted near a seedling, or different grafted variety of Heartnut. Grimo 146 is an early pollinator and is best paired with a late pollinator.
