Drought-Tolerant Plant Selections for Oklahoma

See Extension Circular E-1051 for plant photographs and more information. The plants listed are targeted for Oklahoma City specifically with many also suitable for the entire state of Oklahoma. All selections were chosen for their heat and drought tolerance as well as commercial availability. 


This list is separated by annuals, perennials, ornamental grasses, vines, groundcover, shrubs, trees, and turfgrasses. Each plant is listed alphabetically by its scientific name within each category. The mature height and width are listed, which should be kept in mind when planning a landscape. Each plant has the season(s) of interest shown and light requirements. Many plants listed are considerably more drought resistant when properly mulched. Consumers should note that some listed plant materials can be toxic to pets and humans when ingested. Some plants may cause dermal reactions. People with young children or pets that may ingest landscape plants should check with their garden center or nursery professional
if potential toxicity is a concern.

Improving freeze tolerance in putting green-type bermudagrasses through mowing height adjustments

By Mingying Xiang and Justin Quetone Moss. Learn about how adjusting mowing heights can enhance freeze tolerance in bermudagrasses used on golf course putting greens.
