@RoseBlush1 - I bet there are plants that some people 'round here grow that would work for you. I don't want to be the 1st one to suggest anything since Im too new at this thing called gardening. Are you wanting to grow from seeds?
I do want to applaud you for wanting to grow plants that are more suited to your area. And I especially like that you aren't concerned about having a typical 'yard'. My front 'yard' is taken up my a wonderful Magnolia so everything else is a little St. Augustine, a little Bermuda, some dandelions, a little crabgrass and so on. But when it's mowed it's all green. No problemo!
