Rosie,
You need to try this one and telipogoniflora. You might do well with the "Glass Bubbles" that Orquideas del Valle sells (Untitled Document). The Orchid Picture Blog
I saw when Laura was growing in a glass bubble, looks a great idea. Not sure I can get them on this side of the Pond though.
I'm sure Andrea could ship you some bubbles. They're not plants, so she wouldn't have to wait until a show.
She goes to Europe pretty regularly - here's her schedule page: Untitled Document
Nothing scheduled right now...
Send her an email about the bubbles. andreaniessen@orquivalle.com
