MEDITERRANEAN SURVIVABILTY INDEX ZONE 2B: The Cliff Date Zone
From Palmpedia - Palm Grower's Guide
This is a listing of palms that seem to have survived temps as low as 25-26F/-3.88,-3.33C... however, some show significant leaf damage at that temp, and those palms will be listed at the bottom of the list.
