The USDA divides the United States into seven planting regions, known as hardiness zones, which were most recently updated in 2023. The maps below show these planting regions. Trouble seeing the map?

Zones 1-6 are the coldest, and 7-13 the warmest. Zone 1 averages -60 degrees F while zone 13 never drops below 70 degrees F.

Triple digits are coming fast this year. Here's when Texas normally sees them. Texas has eight plant hardiness zones, ranging from the cold-hardy northwestern Panhandle to the warmer southern regions.
