Yep, i've noted a few times in movies. I'm trying to think of the name of a very old black and white classic movie I saw years ago that starts with an old man in a wheelchair sitting in his 'hothouse' surrounded by blooming cattleyas. (wow) It's an old 'gangster movie' and has car chase etc. in it Name escapes me.
I found a couple of old black and white movies with orchids in them.
