You can search for suitable flowers yourself by going to our Recommended Species page and choosing Oklahoma from the map or pull-down menu. This will give you a list of commercially available native plants suitable for landscaping (and flower beds) in your state. Once you reach the list you can use the NARROW YOUR SEARCH option in the side menu to select "Herb" from GENERAL APPEARANCE, "Sun" from LIGHT REQUIREMENT and "Dry" from SOIL MOISTURE. These choices should give you a good selection of plants that will meet your criteria. As you look at each species page be sure to check the Growing Conditions area to be sure they will match your site. Many of these plants serve as hosts for pollinators—insects and birds. You can find that information in the Benefits section on the species page. You can also find Bloom Information as well as other useful things on the species page.
Here are a few on the list that I thought would work well in your garden, but you may find others you like better:
