Oklahoma Proven Selections

 


  Each spring, Oklahoma Proven’s executive committee announces four new plant selections. Test sites across the state judge the plants based on insect and disease resistance and ability to survive Oklahoma’s climatic conditions with minimal input. In addition, the plant must not have the potential to become a weed.
