December 2022. We had 5 nights in a row at or below lows of 20F. The worst night (2nd night) we hit 12F with a high of 33 the following day and a low of 15F the next night. It was also extremely windy the night before it hit 12F so there was little mercy or benefit to having favorable microclimates.
I still don’t know what will survive in many cases so will update as things progress:
Unprotected plants:
Butia Odorata: 7 large palms (one trunking and the rest near trunking size
