Hi everyone!
I'm new to growing and caring for orchids but I've always loved them. I never thought I'd be able to keep one alive. I have 3, now and I just wanted to make sure that what they are, is what I think they are. My spelling is terrible so I won't attempt, If you could just tell me what you think. I got the white one at a costco, the green/yellow at a big y and the purple/burgandy at a christmas tree shop.

This is my first time posting so if the photos don't work please let me know!













Thank-You
