From what i've heard, Nugget is pretty tolerant of northern climates. It will die back during the frost of winter and then break the soil again in the spring. The first year, it might not produce much and it should be grown in regions that get at least 180 frost free days per year.
Since hops is actually a vine, it can be grown vertically or horizontally. Commercial growers will wrap the vines around a pole, whereas a home grower can trellis it to pretty much any type of trellis system with a wire. Think about a grape vine approach.
