How do you find the Heat Zone for specific plants ? I have fallen in love with many of the plants shown on this site and know many of them can survive quite well in my cold zone of 8a. However, I am finding it difficult if they can thrive in my Heat zone of 8.
This is a quote from the AHS website about heat zones and their heat zone map:
"The 12 zones of the map indicate the average number of days each year that a given region experiences "heat days"-temperatures over 86 degrees (30 degrees Celsius). That is the point at which plants begin suffering physiological damage from heat. The zones range from Zone 1 (less than one heat day) to Zone 12 (more than 210 heat days)."
It's great to know so many plants can survive my winter cold temps, but the idea of having plants that survive the winter and then end up looking fried because they cannot survive my high summer temps leaves me wondering if a given plant should be planted in this garden.
