Thanks for all the suggestions. My orchids are on my screened porch close to the exterior walls of my house, so they are warmer there than if they were outside in the open. One species/cultivar of orchid is actually featured in the article that I wrote which was published last night. I must confess that I don't know much about orchids species. And I no longer have readable labels for them. I've had them for several years. They are the typical orchids you find for sale at big box stores. Not a rare species or anything .... I do love them and their beautiful long-lasting blooms!
I also grow cactus orchids (Epiphyllum spp.). I have many large ones that are full grown from cuttings, but I know that they are succulents, not true orchids. All of these plants are sensitive to very cold temps. But the lowest temps they can handle without being brought in are a bit tricky for me because they are all very near or next to the exterior walls of my house. They are on the north facing side of my yard. So it does get colder there than the full sun, south facing front of my house.
The temps are supposed to go back up into the low 80's in another day. We get those cold snaps, which are for only a night or two. Day temps are supposed to be in the high 60's. So I didn't want to bring them in and then back out again unless it was absolutely necessary.
