Let's see.. I've based the plants on an Indonesian species of Bluey - as it's what we have
so the plants here are most suited for a higher humidity vivarium. The ones I listed were from going into our local DiY store/plant shops and basically taking a picture of everything they had, and researching it later online (ASPCA is a great resource). So just a heads up that there will be many more in the safe/toxic list that I've not included! If you're planning on a Northern Bluey, I can have a peek around if anyone has had success with different plants.
Plants considered
safe: - Bromeliads (avoid types such as Aechmea as they have a large flower or pollen ratio. Need to be mounted on something such as a hard background or driftwood for drainage).
- Peperomia spp. (Peperomia Carperata is doing good, Peperomia Obtusifolia is a pretty green plant that grows well and is also be considered safe - but I suspect it may be stomped on by Bluey's!)
- Majority of 'Spider plant' spp. (Chlorophytum Lemon for example)
- Pilea Glauca (though generally safe, can be irritable if consumed too often).
- Pilea Peperomiodides
- Aeschynanthus Japhrolepis (gets huge..! may not be too suitable for a viv unless you're able to keep on top of preening, similar to aeschynanthus marmoratus)
- Hoya Carnosa Tricolor
- Calathea Rosea
- microsorum diversifolium (while I didn't find any info on toxicity for this one, I'm not sure if the underleaf could be irritating)
- Hibiscus (Bluey's are known to eat the flowers in the wild, so a good natural one!)
- Herbs - they can grow successfully.. we had a watercress in the tank that got huge, but overall they may not last long. Can potentially buy a food safe herb in a supermarket that is already potted up (such as basil, watercress) and replace them once they get destroyed one way or another!
- Airplants - I've lost the species names that we have, but so far not had issues when mounted high in the tank. But can be delicate..
Common plants considered
toxic:
- tradescantia quadricolor (wandering jew)
- Ficus pumila (Ivy; most types)
- Aglaonema (chinese evergreen)
- Scindapsus Pictus Argyreus (or any Pothos spp)
- Sansevieria Laurentii (Mother in law tongue)
- Cordyline spp. (mixed information on this, better to just avoid)
- Passionflower (while generally considered safe, there are some types that are toxic such as Passiflora caerulea or Passiflora foetida. Make sure to thoroughly research if you choose this route).
- Majority of succulent species (sadly.. as love them!)
- Cacti; as you can imagine - avoid them because of the spines

That'd be great to see - love seeing setups
found out when one was pulled down from the background - the one in my profile pic.. it managed to recover though!). If you're able to mount the plant securely to the background, it can do well. We also have a chunky piece of driftwood with a bromeliad attached that is doing fine for the moment. So it's possible by using smaller objects, but be aware they'll still roam straight through/on top of them for fun
