Clematis would look good in there for some height. Some groundcover roses (if you don't want to go big in there) would provide some more color throughout the season and the newer ones are usually easy care. Salvias and coneflowers would look good also. Coral bells would look good along the front since they grow low to the ground and can also provide color if you prefer colorful foliage or you can go with green foliage. Catmint is another great plant to grow and will bloom all summer long.
Oh, these are suggestions for all the beds there in the front.
All would work in a small bed on the driveway also.
You could also make a small vegetable garden there in the area you are wanting to redo.
