Re: Re: temperatures and hardiness

Sorry. Kitty got part A right. A-Z tries to fit plants into USDA [cold] zones. And Noreen got part B right, A-Z's understanding of low temperatures appears to assume a period of duration that does not pertain, at least not in Zone 9 or above. It may or may not pertain in lower zones, but I have no useful experience with them.

You're right Cathy - the AHS heat zones are based on average number of
days per year above 86 degrees. I've got the big map on my wall right
here in my cubicle so I'm reading right from it.


Island Jim
Southwest Florida
Zone 10
