In Florida, we are fortunate to be blessed with a climate that is amenable to growing a wide variety of palms and cycads. However, the same is not true for other palm enthusiasts living in Central Florida, Texas, California, and else where in the US and in Canada. These growers struggle to keep their palms alive. From time to time I hope to update this Table at this website.
Some growers report different experiences with the same species of palm after a cold spell.
The reasons for this involve the nature of the cold spell itself, microclimatic conditions that surround their palms, and the palms themselves. A cold spell can come on suddenly or slowly. The length of time and depth of a hard freeze, wind speed, and ambient humidity can also influence how destructive a cold spell might be. Microclimates and conditions that surround one's personal collection can spell life of death for a palm. A plant sheltered by other trees and shrubs is more likely to fair better than one that is exposed.
