I'm working on the exact same project lol. That's what my large Viv is.
What liana's were you able to get? Where? I am definitely interested.

We should exchange plant findings

. It's hard to find them, the Angrecums are easy, and a few of the common "House Plants" others prove difficult lol. Finding a Madgascar SP of A. Nidus has been a challenge, as was my Tublar Sword Fern (you could sub a Boston, and no one know but you, But I refused lol. Same with the A. Nidus)
That's why I had to have the Madgascarensis, instead of any other Nep. Which sucks, as apparently Madgascarensis use to be popular in the hobby, but people had bad luck with them so they disappeared, and when they pop up they are pricey!
I have a good plant list resource, finding those plants proves difficult.
But this is a good resource, though there is more than listed, it's a good list
