The Grainger Shagbark Hickory was discovered in Grainger county Tennessee in 1935. It has a very large nut for a Shagbark Hickory almost as big as a Shellbark Hickory nut; 3.2g kernel, 143 kernels/lb, and 39% kernel. Grainger bears regularly and shells out easily into mostly halves. It is a good pollinator of other hickories. Good in zones 5 to 8. Good yield, but some susceptibility to leaf blights. Does not store well, as it goes rancid quickly. Nuts fall in mid October in Southeastern Ohio. 3.8g kernel 49% kernel in Ohio.
