I'm still mildly shocked but somehow I've managed to keep the 4 orchids I have alive for several months

. Problem is - I don't know what they are. None of them have that handy little spike thing with the name on it. None have produced flowers yet but two appear to be heading in that direction. Can anyone identify the type of orchid based on a photo of the plant/leaves? I have lots of questions but figured I'd start here. Since they're alive, I'm curious and now interested in making a hobby of this. Thanks. Sue
