I live in an area that sometimes gets a freeze, but in the last 3 winters I have only had to protect my plants on two overnight occasions. (Thanks global warming? eek, what a thought)
These are my personal notes for the plants I own and my own guide organized by temperature so that I know which plants to protect depending on the forecasted temperature. The names for these hard to find numbers are numerous: Cold hardiness/tolerance/damage and Freeze hardiness, tolerance, or damage.
*Please note, there are many variables that effect whether a plant will survive a freeze. An older tree can often survive a hard freeze of short duration. If you live near a large body of water you will have a buffer effect that will create your own microclimate to protect your plants. Plantings closer to your warm house will generally survive. I scavanged the internet for most of these numbers which are only guidelines, please don’t be upset if you lose a plant in a freeze. New growth is more susceptible to damage than mature growth.

Any of the subtropical fruit trees above that dip below the high limit (old or young) will likely loose their fruit in a freeze. Some fruit, like citrus, have improved taste in a near freeze.
