A cross between Simcoe and Imshu, Grimo 146 has much potential with a smooth inner cavity that allows the kernel to be released freely in one piece. 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 a early pollinator and is best paired with a late pollinator.
