Good plants for Vivariums??

I've been looking all over the internet and have yet to find a good answer or even two lists that have the same plants so I thought I'd ask you guys for suggestions! I'm transforming my BP girl's 20g tank into a planted Vivarium and want some good hardy plants to add.
I've also got a empty 12x12x12 cube that's planted with a few small plants from a reptile expo I went to and I'd like to get a larger tank that I'll plant as well for a Crested sometime in the near future so if anyone has any info on plants to add to any of those let me know and share your info!!

Ball pythons are tricky simply because they destroy most vivarium appropriate plants very easily. Larger, sturdier plants that would stand up to a ball python won't really fit in a 18-24" high setup. I have had some success with spider plants that are buried in a ceramic pot, but honestly, I have not had good luck with keeping plants alive after exposure to a 2 kg snake. You might try vining plants like hoya and pepperomia, or if you don't mind trimming, larger ferns and palms would probably have the best chance of surviving a ball python.

Crested geckos are an entirely different story and many plants can be used with them. My crested geckos are in 24" x 18" x 24" or 24" cubes and I too researched non-toxic plants to use with them. Some of the plants I use include:

Fittonia or nerve plants
Calathea - Calathea lancifolia, Calathea 'Beauty Star', and Calathea ornata
Bromeliads - Cryptanthus and neoregalias work well
Ferns - heart fern is my personal favorite (emionitis arifolia)
Peperomia serpens, depressa
hoya curtisii, cummingiana

You can also use jewel orchids, which I love, but you have to be more careful with them as crested can trample them pretty easily. I try and place them low under a branch so the gecko is unlikely to walk on them.

Some I like include -
Macodes pelota, Restrepia brachypus, ludisia discolor, Anoectochilus formosanus, Sarcolexia...the list goes on
