Answer: Some great plants for a slope include Japanese andromeda (Pieris japonica), fragrant snowball viburnum, Burning bush (Euonymus alatus 'Compacta'). Perennials include a selection of daylilies (there are all sorts of sizes and colors), perennial salvia, tall garden phlox, coreopsis. Spring-flowering creeping phlox and prostrate junipers make nice, low-growing ground covers. Any combination of annuals will add extra color, especially for the first few seasons when the perennials are getting established.
