    Do these include windchill factors. What happens in a zone that hits it's low that a particular plant can take....but it's 20 degrees colder with the wind chill?

    Wind speed has no appreciable effect on the temperature at which dormant plant tissue dies. Very dry winds can dessicate plants to the point that the dried-out tissue dies, but this is not affected by temperature, and to a limited extent, 'drier' conditions tend to improve cold hardiness over 'wetter' conditions.
