Arachnis, Renanthera, Ananthera Sources in the U.S.

[peeweelovesbooks]

What is a good source (In the U.S) for these plants? I've been looking but haven't found any. Are they hard to find?

Also, what potting medium if you want to grow these in pots as opposed to putting them in baskets? I'd like to grow them here in Miami outside in my porch. Thank you to the chat members who suggested something that won't die out there in the full sun.

I'm specifically looking for:

Renanthera imschootiana
Renanthera Nancy Chandler
Renanthera phillipinensis
Renanthera bella
Aranthera Anne Black
Arachnis flos aeris.

Thank you!
