I was wondering about this. Zone 6, USDA zones, has winter temps of 0 F to
-10 F, and I don't think Shcreiner's gets this cold, or does it? Here in
zone 6, USDA zone, in middle Tennessee, our expected frost-free period is
about April 15 to Oct 15. The Sunset Western Garden Book has its own set of
zones. I noticed that the Zone finder on the Internet lists both sets of
zones. Gigi, are you lurking out there? Or Rick, are we talking about two
different sets of zones?
