The name 'Imshu' is a blend of 'improved and 'Schubert'. It originates from Korea and it is said it was brought to North America by a soldier who served in the Korean war. 'Imshu' is a heavy producer of medium sized nuts that, if cracked carefully, will crack out whole kernels that drop out of the shell freely. Nuts ripen and begin dropping in the last week of September. Cold Hardy to USDA zone 6.
Partially self-fertile - can produce much more if planted near a seedling, or different grafted variety of Heartnut. Imshu is a late pollinator and is best paired with an early pollinator.
