I would definitely not march a uniform shrub across the front of the house, ignoring the grade change and architectural features. (A single shrub below the double windows could get large enough to fill that spot.) Here are some general ideas ...

Just as a horticultural note, roses and hostas do not really enjoy the same growing conditions. Roses need full sun and hostas are more of a shade plant.

Also, I always encourage clients to include evergreen material by an entry planting so that there is always a presence and something of interest in winter as well as summer. In MD, there is a wide range of broadleaved evergreen plants available for this purpose, including many that flower, like rhododendrons, azaleas, gardenias, etc. And many suitable dwarf conifers (needled evergreens) as well. Mix in some colorful annuals, perennials and groundcovers - as Yardvaark suggests - and you have a garden that appeals in all seasons, not just summer.
