9a/9b Epiphytic Orchids? (& WIP spreadsheet)

[Calosphace]

Hi, everyone! I'm new to orchids and had been lurking here while researching varieties I got this year. I am only interested in growing orchids that I can keep outdoors year-round as I really like them mounted on trees specifically and interacting with pollinators. I am in zone 9b (2023 zone map) in Northeast FL, so what I grow has to be heat tolerant but also capable of taking quick, dry cold (e.g. overnight freezes).

I am working on a spreadsheet of epiphytes that can take freezes and one of the tabs is for orchids. It is here: Hardy Epiphytes Reference - Google Sheets

The list is a combination of grower information and zones of natural distribution (I use iNat for this), doesn't guarantee trait is consistent across individuals but it at least gives an idea I hope.

This is all to say, I would be very interested if anyone here has experience growing species and them surviving freezing conditions. I can add them to the list (and my cart lol). For high-altitude species I will probably make a column for heat sensitivity.

This year I have acquired the following orchids and have been growing them outdoors no watering nor fertilizer:
Encyclia tampensis var. alba
Encyclia tampensis
Cattleya cenua
Laelia anceps albiflora
Laelia anceps var Guerrero
Phalanopsis / Sedirea japonica
Dendrobium nobile 'Smile' [this one is in hanging pot as it came in a nice one so I feel no need to mount it]
Dendrobium moniliforme 'Kouga'

Next up I plan on getting a Neofinetia falcata and any hybrid of Epi. magnoliae with an exotic I can find
