"Most first frosts occur from a strong cold spell that followed
many days of warm weather.  Our long growing season and
mild fall temperatures allows many plants to continue to 
grow until true cold weather arrives. When this occurs, many 
of our tender plants, especially houseplants and bedding 
plants, are caught off guard by the changes in temperature 
and may get damaged or killed.  Woody plants that are 
adapted for our area typically survive without problems."
