I guess we can plant things at least a zone warmer than we could last year *lol*, and tell those plants to see the new zone map.
I'm firmly 7a now and within 20 miles of 7b. I was either 6a or 6b when I was a kid here.
Of course I now enjoy sabal palms, passionflowers, salvia greggii, lantana, crinums, and have cannas I can NEVER kill. Things are changing....
