North Texas landscape design question

Question

We recently purchased a home that is situated on a large corner lot. A large portion of the lawn is in desperate need of landscaping. We planted one small crepe myrtle (which we are considering transplanting to the back yard). We have purchased four other crepe myrtles (one large one and three that are a little smaller ~ see picture). What, along with the crepe myrtles, can we plant to take up a large portion of this corner of our yard? We'd like to add some ground cover so we don't have to mow the area and also add texture and interest to an otherwise very boring corner. I've added a link for pictures of our yard. Thanks!

I live in the UK so the only suggestion I can offer is to go into Encarta for this one. Good luck h
