G'morning, gents, and thank you for the replies.
The story here is that my German ancestors emigrated from Alsace (where they brewed their own beer) to Ukraine (where they brewed their own beer) to the Killdeer Mountains of Dunn County, North Dakota (where they continued to brew their own beer).
Fast forward to a couple of months ago, when my dad and I were talking; he mentioned that on the site of the North Dakota town where they settled, hops are still growing on their own, as he discovered last summer. It didn't take long to get the idea to attempt to transplant some of these hops here, where the climate is very, very similar.
I do have family in North Dakota that could probably collect some shoots if it would be better to get them in the ground during the fall or winter, but for realistic purposes, it will probably be next spring before I am able to move forward on this. I know that with some plantings, you want to get the cuttings late in the fall or the winter, and then plant them in time to "wake up" in the spring. This is my current plan, but I am very open to suggestions about the best way to get them started.
