About this seed family

The Whitten line is split into north and south selections. This is the northern half, taken from parent trees that handled colder conditions.

You get hybrid nut size with a better hardiness margin than most European crosses.

A reasonable bridge family for growers who want to try hybrids without full winter risk.

What you are actually buying

This is a seedling grown from a nut produced by a named Whitten North Family parent tree. It is not a grafted clone and we will never sell it as one. It inherits roughly half its genetics from that known mother tree and half from whatever pollinated her, which means you get a real head start on quality plus the seedling advantages of a natural taproot, lower cost and genetic diversity across your planting.

Every tree is started in our insulated shed under grow lights and grown in a 4 inch by 12 inch deep tree pot, so you receive a well-rooted young tree with a developing taproot rather than a root-bound plug.
