That's a pretty good situation, morning sun and afternoon shade, because it opens up the possibility of using plants that don't want full sun. I designed a landscape for just such a ranch-style house a year ago. Here's what worked for me: 'Karen' azalea (spring flowers and fall foliage); 'Golden Spirit' smokebush; ajuga groundcover; Caryopteris 'Sunshine Blue'; redtwig dogwood (although it requires a lot of trimming, so if you use it, position it where it won't block a window); mums; asters; yews and juniper (the latter already existed in the landscape, but I found they made a nice backdrop for the chartreuse foliage of the Caryopteris and smokebush).
