We have had thornless blackberries for several years. They have done very well. I freeze a lot of the berries spread out on a cookie sheet, then pop them into ziptop bags when they are solid. These are great (in the frozen state) for making smoothies. Here's a picture of frost on the bushes. Five of the 6 blueberry bushes we planted are continuing to do well.
The three old cherry trees in the front yard got too wild to get any fruit below "bird level" and I am getting a bit too old and shaky for stepladders. I saved several volunteers from pits and we transplanted 10 of them to the side garden, where they are now bearing fruit. Almost lost them with the locusts a couple of years ago--didn't realize what was scarring the tender branches until damage was done, but they are all OK. I just hope to get the fruit before the birds do.
I started thornless red raspberry bushes a couple of years ago, but really need a new more plants since they are my favorite fruit. I started two elderberries the same year, but between a lawn mower (despite the flag at the plant) and a horse that got loose, one of them is barely surviving. There seem to be enough wild ones around to pollinate the other one though.
The Arbor Day Foundation has a hazelnut research program we have participated in for several years; they have produced nuts the past couple of seasons. We also have pecan trees and chestnuts that are nearing their end stages, but I have raised some chestnut saplings from seeds that took root. Need to transplant some of them.
