Here's a report on the Dec 2013 freeze.

Strong radiational freeze, my garden is on a hillside, lower garden got nailed pretty hard by cold drainage and wind protection. 5 nights below freezing for 9 hours or less per night, worst night was 26.6F, see data and graphs below for details.

Not a trace of damage, specimen full exposed. Note that a potted parajubaea sunkha 2 feet away got significant frost damage (probably not hardened off.)

Dec 4/5: 57.4F high, below 32F at 11.17PM steady decline to 26.6F at 7:30AM with a dewpoint of 16F. above freezing 8:47AM

Dec 5/6: 57.4F high, below 32F at 11:30PM steady decline to 29.8F from 4:30AM to 7AM, above freezing 8:30AM

Dec 6/7: 55.9F high, 50F overnight with 1 inch of rain

Dec 7/8: 53.1F high, below 32F at 11:30PM, steady decline to 28.6F, above freezing by 8:45AM

Dec 8/9: 55.9F high, below 32F at 11:30PM, steady decline to 28.6F, above freezing by 5:30AM
