Last night was our coldest night of the season - and in the 'cold pocket' of my garden, the side where the vegetable beds and perennial border are, there was a light frost and freeze. The peppers and tomatoes and eggplants are now gone. The citrus trees (a satsuma, lemon, kumquat and mandarin orange) were packed with straw around their pots and covered in a tarp, and they are fine (I harvested five satsumas a few days ago, and just ate the last one this evening). Fortunately most of the perennial border is covered by tree branches - either live oaks or river birch or bald cypress or sweet gum - so the fall-blooming salvia and milkweed and mexican sunflower etc are fine. The lettuces, tuscan kale, swiss chard and other fall crops recovered quickly from the cold during the 60 degree afternoon. Temperatures will be in the mid-70s this weekend.
