I'm afraid you've moved from Heaven to Hades for gardening. Your part of Texas is often brutal. A full sun description for a plant usually does not mean full sun in Texas. A high profile plant or container may need to be anchored down due to the wind. I hope your patio faces east and not south or west. That will give your plants some break from direct sun and, to some extent, from the directions where the wind tends to be high. Heat is the other factor. In summer, triple digit days are not rare at all. Worse for many plants are nights that do not cool down enough.
That's a lot of negativity, but there are still plants that manage and look nice. I'd say look around and see what may be growing in the area that you find appealing. Ask and find out if there are any local specialty nurseries for plants. They will probably be carrying plants more specific to Midland than the box stores that have them shipped to stores covering a wider area.
