Heritage can do OK in zone 4. I'm 150 miles north of the Twin Cities and grow them. I prefer my Boyne though. Excellent flavor, very cold hardy.Good producer.

Currants and blueberries form bushes. Raspberries form canes and will not be as attractive, especially in winter. For raspberries as a landscape plant, try planting a double row, closely spaced, and keep all the canes pruned to the same height once growth has slowed in late summer.

Thanks for the recommendations! I can't seem to find any good images online of the plants themselves. Do you have any recommendations for plants that grow and stay more vertical than the variety that sprawl out? I didn't ever know the variety, but I had a few raspberries at my last house that grew like this. They didn't really sprawl out and invade the nearby bushes so they looked fairly good.

Thanks again for all the help!

The only raspberry plants I think look good as landscape plants are black raspberries. I had planted red, purple, yellow raspberries on my fence in the back yard, then ran out of room, so I planted my 3 small black raspberry plants along the left side of my home.

They quikly grew larger, and filled in over the next year, and since they grow more like blackberries than raspberries, they grow out of the same central spot, with lots of canes from that one central area. I had 3 bunches of them growing, and they start out the 1st year as powdery blue-green colored canes, then in fall, they change color to a powdery burgundy color, and stay that way til they fruit the next season. But every season, new 1st year canes come up which are powder blue-green colored.

I thought they looked good there is not allowed to grow too long. They are sweeter than other raspberries too, and the Cumberland variety I grew was extremely productive!

Agree that black raspberries (black-caps) can be more attractive as a landscape plant. Widely-spaced plantings can form fountains of blue-green canes (arching habit). Downside is thorns and an acquired taste (of the fruit, for people in general).

The only way you can guarantee vertical raspberries is to include a minimal trellising system, or keep them pruned between waist and shoulder high (will reduce fruit production).
