OT-PLANTS: Syringa

      The amount of chilling within a zone is not consistant throughout the 
zone.  That is one of the problems with the USDA Zone system.  In the U.S., 
the Sunset Zones take this into account. 
      In the west, USDA Zone 8 and most of Zone 9 get significant chilling 
hours.  In the eastern U.S., it is much different.  Cold snaps usually have 
times of warm to hot weather between them, even in winter.  While this does 
not harm some plants such as Cornus florida or Cercis canadensis, it does 
eliminate the use of some species such as Forsythia, Syringa, or Malus.
