When freezing temperatures threaten, we can take steps to insulate plants against the cold. For brief freezes, you can simply cover plants with blankets, towels, burlap, or other insulating materials.

22% set the temperature below 68°F Residents of Maine, Connecticut, New Hampshire, Oregon, and Wisconsin keep their thermostats the coolest come winter, at 67°F to 68°F.
Most houseplants are species that have adapted to survive in a temperature range between 15 and 25 °C (59 and 77 °F) year-round, as those adapted for temperate environments require winter temperatures outside of normal indoor conditions. [4]
A chilling unit in agriculture is a metric of a plant's exposure to chilling temperatures. Chilling temperatures extend from freezing point to, depending on the model, 7 °C (45 °F) or even 16 °C (60 °F). [3] Stone fruit trees and certain other plants of temperate climate develop next year's buds in the summer.
The low latitude and often stable weather in Florida, the Gulf Coast, and southern Arizona and California, are responsible for the rarity of episodes of severe cold relative to normal in those areas. The warmest zone in the 48 contiguous states is the Florida Keys (11b) and the coldest is in north-central Minnesota (2b).
However, even if colder temperatures are mitigated, most crops will stop growing when the days become shorter than 10 hours, and resume after winter as the daylight increases above 10 hours. A hothouse — a greenhouse which is heated and illuminated — creates an environment where plants are fooled into thinking it is their normal growing season.
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
