Actually, Im not really into orchids but people give them to me occassionally so I do have a few. I usually just attach them to one of my tree ferns (hapuu) and forget about them until they bloom. Here's a couple of the common ones. Don't know the names. sorry
They're beautiful. You're lucky to be able to grow them. I have bought them for myself and I kill them all eventually! UGH They're in bloom when I buy them, then the flowers die.... it's only a matter of time before the whole thing poops out on me!!
