What zone 8b means for El Paso
Hardiness zones are based on the average of the coldest night of each winter over 30 years (1991 to 2020). In zone 8b, that average is 15 to 20°F (-9 to -7°C). Plants labeled hardy to zone 8b or colder should survive a typical El Paso winter. A plant rated only to a warmer zone will need a sheltered spot, a pot you can bring inside, or treating as an annual.

Choosing plants for zone 8b
When you shop, look for the hardiness range on the tag or in the catalog, such as "zones 4 to 9". Pick perennials, shrubs and trees whose range includes 8b. If you are set on a plant rated only to a warmer zone, plant it in a sheltered spot against a south-facing wall, mulch the roots before winter, or grow it in a container you can move into a garage. Zones only cover winter cold, so also check sun, water and soil needs. More in how to read a plant tag.
