I don't know where AHS got their temperature recommendations from, but 
most of the ones I've checked--and I don't check them that often--way 
understate the hardiness of most so-called tropicals. Half the plants 
in my yard would not survive, let alone flourish, if AHS numbers were 
Amen.  Although I have noticed that the difference is that in zone 9 and 
higher the temps don't stay low for long....only an hour or two then back up.  
Perhaps this is their way of averaging the temps.  For instance, a plant might 
survive fine with a dip down to 32 for a short time, but might not survive if it 
stays around 32 for days on end.
