Forest Agriculture Enterprises LLC www.forestag.com has nursery stock that is currently in variety trials in MN, WI, MI, IA, IL, and NY. It's the only nursery east of the rockies that has a controlled-cross breeding program, and also happens to be the nursery that is totally sold out 1 year in advance already...
For more info on hazelnuts east of the rockies I recommend checking out the Hazelnut Improvement Program.
