There are many great choices to consider. But the choices can be narrowed down, when you consider available space and size of the shrubs of interest when they have become full grown. You'll want to be able to plant far enough away from your house so that it is at least half of the full grown width of the shrub away. Add more distance to this if you anticipate needing to get something like a ladder behind the plantings for home maintenance, and/to allow for adequate light and air circulation. Amount of available sunlight also plays a role for making your selection. Your preferences as to evergreen or deciduous shrub, as well as the overall shape, are also important to consider. The link below divides some shrub possibilities into groupings based on size. http://www.extension.umn.edu/garden/yard-garden/landscaping/fitting-trees-and-shrubs-into-the-landscape/index.html And some additional information on choosing shrubs in Minnesota. http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/ In addition, if you are able to visit the Minnesota Landscape Arboretum, they have an excellent shrub display that allows you to see the mature size and shape of some shrubs in a natural setting.
