looking for nuts

Hi
I a looking for nuts to plant trees. Looking for English (carpathian) walnut, and hazlenuts. I am on the edge of zone 5/4 so that why looking the Carpathian version of the English walnut which is hardier then normal English.
If anyone has ideas of who would sell these I would appreciate it

Thanks
Gary

Assuming you are in America I would start with North American Nut growers (http://www.nutgrowing.org/). You will find many states have a local chapter.
When it comes to nuts these folks have the goods.

i feel a bit redundant cause i posted this link a bunch of times, but i have spent too much time looking over all their awesome hard to find tree seeds...i know they have many different walnuts, chestnuts and other cool nuts for seeds

so here a link to the tree and shrub seed website:

As with apples, trees planted from seed vary considerably. Commercial orchards all use grafted trees.

Nuts have been bred for larger size, easier nut-meat extraction, easier husk separation, less bitterness etc...

I'd recommend buying some grafted trees to experiment with. If you later plant some seeds you can then graft them from your own trees.

They strongly discourage planting actual hazelnuts though. The sell live plant in "tublings" from about May-July. Very good/interesting breeding program.
