Chinese evergreen is the answer. They tolerate low light better than most other plants. You might also want to consider setting up a desk lamp with a CFL in the 6500K range to offer a bit more light and give you some more options.

The Texas Everbearing sold by some large home-improvement chains in Austin, Texas is a mediocre fig similar to California Brown Turkey or Black Jack. My Black Jack is generally killed to the ground by the first hard winter freeze. Alma is a little more cold-hardy than Black Jack, but still susceptible to cold damage. A point for Alma is that it is a late bearer (Sept., Oct.) and would be a nice complement for Celeste, which bears in June or early July in Austin. Other varieties that I would recommend on the basis that they have some cold resistance, are not extremely large trees, constrast considerably in appearance from Celeste and have exceptionally good flavor are Negronne (Violette de Bordeaux), Adriatic (Grosse Verte), and Hardy Chicago. Good luck with the new addition! *** BTW, I usually post as mountainman0826, but for unknown reasons, Gardenweb's log-in has changed my posting nickname.

Perhaps it is not necessary to add more mulch for clematis in my area as most winters we have good snow coverage. But some winters, not so much. When I attended local gardening workshops the pros always emphasized winter mulching, but, they mostly admitted that they themselves do not add winter mulch. So, who knows? Since I collect the neighbors' shredded leaves to compost and mulch other plants around the clematis I add it to them as well. Most clematis die back to near the ground for me. My hope is that covering the prune 2 clematis well will keep more of the stems alive higher so I can get that early spring bloom on old wood. Sometimes it works. The clematis I grow from seed and from cuttings are kept in pots and put in the ground in holding beds. These I don't want to take a chance of losing so they get completely covered by shredded leaves for the winter.

Ornamental grasses would give you texture in a wide range of colors. One of my favorites is little bluestem, most of the sold varieties aren't "green" but rather a powder blue color. They turn an amazing pink/copper color in the fall though which I LOVE. They stay fairly compact. Blue grama "blonde ambition" gets to be around 3'x3' and contrary to it's name, isn't very blue IMO. It's actually more of a "spring green." It gets loads of little yellow seed heads on it and then the foliage itself dries down to a straw color in fall. Another favorite of mine is switchgrass. There are both blue and green varieties of this, and it might get a bit bigger than you want (I think some get to be like 3'x4' tall). However, it's another great one. I have "Shenandoah" which is a green one that gets spatterings of deep maroon as it starts to cure in the fall. Blue avena grass is a compact grower, and I THINK it's semi-evergreen too (mine tends to keep quite a bit of color in the foliage through the winter). But, once again, it's blue rather than green. Blue fescue is an adorable little plant. So, if you're looking for small small, it doesn't get much more than 1'x1'. Sold varieties are blue, but, if you are willing to start your own seed, you will wind up with mostly green ones (they are actually very easy to start from seed, you will just have to be patient as you wait for the plants to size up) I hate to add this one to the list because it is hands down my LEAST favorite grass, but feather reed is a VERY popular one that would definitely work for you I think. If you have the room, big bluestem is another great looking grass, but as it's name suggests, it get's big. Those are just a few, but there's probably close to a gazillion OG's on the market these days for all kinds of conditions. If you are looking for texture, I would definitely put some on the short list. I will also try to add some pictures soon for you to since I have all of those (except BB) in my yard.
