Plant Hardiness Zones in Oklahoma

Areas in Oklahoma Where Plants Are Most Likely to Thrive

Not all plants thrive under the same temperature and climate conditions. Therefore, it is important to know your state’s climate zone so you know what plants you can successfully grow there. Most gardeners use the USDA Hardiness Zone Map to determine what plants thrive in a specific location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Below is the growing zone for Oklahoma. Oklahoma’s climate ranges from humid subtropical in the east to semi-arid in the west. Summers tend to be long and hot here. The time in which you should plant your seeds or transplant them outside depends on what planting zone in Oklahoma you live in. We recommend growing lettuce, kale, snow peas, and spring onions here.
