And the USDA zones are a damn-fool idea anyway, as they measure an
extreme value rather than a central one, and that is NOT a
reliable//////////////Bottom line.......I find them very useful when
combining with other factors........far from being a "damned fool
idea"........I would not consider growing a plant listed as zone 8 min. when
I am in zone 6 (regardless of other factors)........I also admit the a plant
listed for zone 7 might not be in my grow list for other climatic reasons.
