Mini bulbos entwined on terrarium background?

[Fishkeeper]

If I have two bulbos of roughly the same leaf size, can I put them right next to each other and let them twine together? Assuming neither is one of the species that crams itself really tightly together until you can't see the mount for the bulbs.

When you see a big, well-grown specimen bulbo, it isn't just a crammed mess, with flattened bulbs and crimped leaves. It figures itself out and spaces itself. Since old growths can't exactly move out of the way, I assume this process is done by the growing ends. So, if I have two bulbos right next to each other, will they grow entwined without hurting each other? Or will they fight each other and wind up with two unhappy plants, or one happy plant and one smothered one?

I'm specifically looking at B. fascinator and B. treschii. I like both, and want both in my terrarium, but I'm a little low on space. They seem to have the same care requirements. So I'm curious what would happen if I put them right next to each other and let them get tangled. Assuming they wouldn't hurt each other, the only trouble I can see is that it would be a bit of a puzzle to figure out which was which, if I was trying to take a cutting/division.

Or, what would happen if I put one of the micro bulbos, like B. alagense, right next to one of these? Would it climb over the roots of the bigger one and make a neat contrast, like moss does, without hurting the bigger one? Epiphytes seem much more tolerant of cramming and overgrowth than soil plants. And I know I've seen pictures of healthy mini orchids with moss growing live all around the bases. If they do well with dense moss over and around their roots, I'd imagine a less dense clump of micro bulbos would be harmless enough.

I guess what I'm basically getting at is, can you stack orchids, assuming none of them are easily able to shade the other out completely?

I am growing both of those and they are quite large for a terrarium

From the pictures and descriptions I've seen, it looks like B. fascinator is about 3" from leaftip to bulb base, and B. treschii roughly the same size. On the upper end of what I'd want to keep in this, but I think a relatively small plant would be fine. Are they bigger than I think?

Here’s what I found.

I think treachii is accurate but my feeling was because it grows large fast. Mine is on a wet mount and soaring.


I do not grow fascinator I grow fascination. Which is large.

I guess that is the issue, all the spreading. Still tempted to try.

How do you think the two species would do kept as houseplants, in relatively low humidity? If they'd do fine, I could just take them out and pot them up if needed.

While I'm at it, does B. treschii need any sort of prompting to re-bloom? I can't find much about it online, mostly it's just generic info.
