The lowest I saw was 37. I just walked around the house and the only thing that looks bad is the porterweed, and it's been on its usual decline for a week or so now. It bounces back super fast in the spring, so I just have to look at it be ugly for a few weeks. Of course, it doesn't help that I planted it right in front of the walkway to the house.
Everything else looked fine including Bromeliads, Jatropha, and even my Brugmansia! And look, my Passiflora 'Lavender Lady' is covered in blooms. Only found one caterpillar. They get their time with the plant; I get mine. All's fair in the garden.
