It's a temperature range for an area that indicates by number which plants can survive there year round. You can read more in source.

No. The low end of hardiness is 26 degrees, and only for brief periods.
Sunny winter days cause the phloem cells to lose cold hardiness. Plants warm up during the day, and are susceptible to damage at night when the temperature drops. Losing cold hardiness leads to sun scald and bud and stem death.

USDA hardiness is a guide to selecting perennial plants that tolerate the winter temperatures in your area. It is a map of the United States and southern Canada that is divided into 11 areas based on 10 degrees Fahrenheit difference in the average yearly minimum temperature. Knowing your zone and finding out what the hardiness zone of a plant is, it tells you what plants are hardy in your area so that they survive through your winters.Greenhouses, nurseries, and stores usually sell perennial plants that state the hardiness zone as a range of zones, such as zones 4 to 9, on their labels.
It tells you which plants can usually grow unprotected in your area. If you live in zone 6, and a plant you want to grow is hardy to zone 6, you can grow that plant unprotected all year. If its only hardy to zone 7, you need to protect it for the winter. In general, if a plant's hardiness zone is less than or equal your garden zone, it needs no protection. If greater, protect it.
