Thanks! Never thought of fake plantsLive plants are usually harder to maintain especially on a T enclosure. Try using fake ones instead. I've seen realistic ones sold in a dollar store.
But if you must, then you can't go wrong with Pothos (aka devil's ivy). You can also use Syngonium (looks kinda like an arrowhead, only viney). I've used both in some of my T enclosure, and they're pretty tolerant. For you're G rosea tank, I wouldnt put any live plants at all. G roseas like it arid, while plants need a bit of watering once in a while. You can also put Tillandsias in your tank. Just have at least 3 available and rotate each one once every 2 weeks (2 in your window, 1 inside you tank). This way, each of your plants will get enough sunlight.
Other plants I've used in my reptile/amphibian terrariums were:
Succulents (Jade plants, Aloes, etc..) (needs very intense light, but less moisture)
Bromeliads (Bright colors will fade to green if you don't have intense lighting)
Earthstars (Bright colors will fade to green if you dont have intense lighting)
Anthuriums (slow grower, but has really wide leaves that create shade)
Ficus (benjamina and elastica)
Codiaeum (needs intense light for brighter leaf colors)
Some philodendron species
Mind-your-own-business plant (aka baby tears) - I had to take this out since some parts have gone moldy
Fittonia - needs high light and moisture - mine became tall and leggy due to not enough light
Flame violet - needs high light and medium moisture - mine became leggy due to not enough light, some leaves have gone moldy too due to too much moisture.
Mango (I just planted a seed to see how it goes and it's still alive after 3 months; I'll try avocado next)
Most of these require higher lighting which some arachnids will hate, and also higher moisture
Good luck and happy landscaping!
