From February 2012 advective freeze.
The ultimate low temp is unknown. I had a 15 gallon A. minima left outside when the forecast low was to be about 37F/2C. Cold front came through about 4am local time and dropped the temperature from about 40F to near freezing in two hours with high winds. Water in bird bath was frozen. There was no frost. The palm had no overhead protection, but it was sheltered from the NW wind by the house and the orchid shadehouse, as well as the fronds of other neaby palms of similar size. A week later there is no damage other than some minor leaf spotting on one of the more exposed fronds and some slight burn. Temperature was likely not below freezing for more than an hour or two.
Inland Central Florida, 28N, 81W. Humid-subtropical climate with occasional frosts and freezes. Zone 9b.
