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.)
