Thanks for writing. I'd typically look at a fast-growing groundcover so you have something to cover the area pretty quickly. Once a groundcover was established, I might consider adding shrubs, perennials, or even a small tree, depending on how the area looks.
As to what groundcover....that depends on where you live, if the area is in sun or shade, what type of soil you have, etc. I'd take a look through our Plant Encyclopedia on BHG.com for more ideas.
