Once you get to MN, you'll no doubt be going to a garden center to pick up replacements for the junipers. Ask the plantspeople what would be the best for your folks' conditions. Quite a few different kinds of conifers to consider. Spirea, hydrangeas, potentilla, barberry, alpine currant, northern grown viburnum (Emerald Triumph), honeysuckle, ninebark, lilacs, forsythia are all pretty common shrubs here and there are many more I know nothing about. For a ground cover there's always the creeping juniper types.
